Further enhancements to the userspace ethtool implementation that was
submitted in 2.1 and packaged as a self-contained sample application.
Implements an rte_ethtool shim layer based on rte_ethdev API, along
with a command prompt driven demonstration application.

This patchset depends on http://dpdk.org/dev/patchwork/patch/6563/

v2:
* Replaced l2fwd base with simpler application.
* Added ringparam functions.
* Added documentation.

+
+EthTool Sample Application
+==========================
+
+The Ethtool sample application shows an implementation of an
+EthTool-like API and provides a console environment that allows
+its use to query and change Ethernet card parameters. The sample
+is based upon a simple L2 frame reflector.
+
+
+Compiling the Application
+-------------------------
+
+To compile the application:
+
+#.  Go to the sample application directory:
+
+    .. code-block:: console
+
+        export RTE_SDK=/path/to/rte_sdk cd ${RTE_SD}/examples/ethtool
+
+#.  Set the target (a default target is used if not specified). For example:
+
+    .. code-block:: console
+
+        export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+    See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+
+#.  Build the application:
+
+    .. code-block:: console
+
+        make
+
+Running the Application
+-----------------------
+
+The application requires an available core for each port, plus one.
+The only available options are the standard ones for the EAL:
+
+.. code-block:: console
+
+    ./build/ethtool [EAL options]
+
+Refer to the *DPDK Getting Started Guide* for general information on
+running applications and the Environment Abstraction Layer (EAL)
+options.
+
+Using the application
+---------------------
+
+The application is console-driven using the cmdline DPDK interface:
+
+.. code-block:: console
+
+        EthApp>
+
+From this interface the available commands and descriptions of what
+they do as as follows:
+
+drvinfo
+        Print driver info
+eeprom
+        Dump EEPROM to file
+link
+        Print port link states
+macaddr
+        Gets/sets MAC address
+mtu
+        Set NIC MTU
+open
+        Open port
+pause
+        Get/set port pause state
+portstats
+        Print port statistics
+regs
+        Dump port register(s) to file
+ringparam
+        Get/set ring parameters
+rxmode
+        Toggle port Rx mode
+stop
+        Stop port
+validate
+        Check that given MAC address is valid unicast address
+vlan
+        Add/remove VLAN id
+quit
+        Exit program
+
+
+Explaination
+------------
+
+The following sections describe the most important parts of the code.
+
+
+Base program
+~~~~~~~~~~~~
+
+The top-level, after some port initialisation routines, runs the following:
+
+.. code-block:: c
+
+	for (idx_port = 0; idx_port < cnt_ports; idx_port++) {
+		ptr_port = &app_cfg.ports[idx_port];
+		rte_eal_remote_launch(slave_main, ptr_port, idx_port + 1);
+	}
+
+	ethapp_main();
+
+Each slave core, or a subset of these cores if there are more cores then
+NIC ports, runs the `slave core process`_ described below. The master core
+then runs the `EthTool App`_ itself.
+
+
+Slave core process
+~~~~~~~~~~~~~~~~~~
+
+Each slave core is assigned one of the available ports, and runs
+the following code that implements a simple MAC frame refector:
+
+.. code-block:: c
+
+	while (!ptr_port->exit_now) {
+		rte_spinlock_lock(&ptr_port->lock);
+		if (ptr_port->port_active == 0 ) {
+			rte_spinlock_unlock(&ptr_port->lock);
+			continue;
+		}
+
+		/* Incoming frames */
+		cnt_backlog_frames = ptr_txq->cnt_frames;
+		cnt_recv_frames = rte_eth_rx_burst(
+			ptr_port->idx_port, 0,
+			&buf_recv_frames[ptr_txq->cnt_frames],
+			MAX_BURST_LENGTH - cnt_backlog_frames
+			);
+		if (cnt_recv_frames > 0) {
+			for (idx_frame = 0;
+					idx_frame < cnt_recv_frames;
+					idx_frame++) {
+				ptr_frame = buf_recv_frames[
+					idx_frame + cnt_backlog_frames];
+				process_frame(ptr_port, ptr_frame);
+			}
+		}
+
+		/* Outgoing frames */
+		if (ptr_txq->cnt_frames > 0) {
+			cnt_sent = rte_eth_tx_burst(
+				ptr_port->idx_port, 0,
+				ptr_txq->ptr_frames,
+				ptr_txq->cnt_frames
+				);
+			/* Shuffle up unsent frame pointers */
+			for (idx_frame = cnt_sent;
+					idx_frame < ptr_txq->cnt_frames;
+					idx_frame++)
+				ptr_txq->ptr_frames[idx_frame - cnt_sent] =
+					ptr_txq->ptr_frames[idx_frame];
+			ptr_txq->cnt_frames -= cnt_sent;
+		}
+		rte_spinlock_unlock(&ptr_port->lock);
+
+	} /* end for(;;) */
+
+There is a check to make sure the port is in an active state. A burst
+of frames is read and each frame within this burst is processed as
+described below. Outgoing frames are then dispatched as a single burst,
+with unsent frames being shuffled to the front of the outgoing queue if
+not all of the frames could be sent.
+
+The processing of individial frames consists of setting the destination
+address to be the source address, setting the source address to be the
+MAC address of the port being handled, and then queueing the frame for
+transmission:
+
+.. code-block:: c
+
+	ptr_mac_hdr = rte_pktmbuf_mtod(ptr_frame, struct ether_hdr *);
+	ether_addr_copy(&ptr_mac_hdr->s_addr, &ptr_mac_hdr->d_addr);
+	rte_eth_macaddr_get(ptr_port->idx_port, &ptr_mac_hdr->s_addr);
+	ptr_port->tx_queue.ptr_frames[ptr_port->tx_queue.cnt_frames++] =
+		ptr_frame;
+
+
+EthTool App
+~~~~~~~~~~~
+
+The ``foreground`` part of the EthTool sample is a console-based
+interface that accepts commands as described in `using the
+application`_.
+
+.. code-block:: c
+
+	ctx_cmdline = cmdline_stdin_new(list_prompt_commands, "EthApp> ");
+	cmdline_interact(ctx_cmdline);
+	cmdline_stdin_exit(ctx_cmdline);
+
+
+Individual call-back functions handle the detail associated with each
+command, which make use of the functions defined in the `EthTool interface`_
+to the DPDK functions.
+
+
+EthTool interface

+
+The EthTool interface is built as a separate library, and implements
+the following functions:

+
+Keep Alive Sample Application
+=============================
+
+The Keep Alive application is a simple example of a
+heartbeat/watchdog for packet processing cores. It demonstrates how
+to detect 'failed' DPDK cores and notify a fault management entity
+of this failure. Its purpose is to ensure the failure of the core
+does not result in a fault that is not detectable by a management
+entity.
+
+
+Overview
+--------
+
+The application demonstrates how to protect against 'silent outages'
+on packet processing cores. A Keep Alive Monitor Agent Core (master)
+monitors the state of packet processing cores (worker cores) by
+dispatching pings at a regular time interval (default is 5ms) and
+monitoring the state of the cores. Cores states are: Alive, MIA, Dead
+or Buried. MIA indicates a missed ping, and Dead indicates two missed
+pings within the specified time interval. When a core is Dead, a
+callback function is invoked to restart the packet processing core;
+A real life application might use this callback function to notify a
+higher level fault management entity of the core failure in order to
+take the appropriate corrective action.
+
+Note: Only the worker cores are monitored. A local (on the host) mechanism
+or agent to supervise the Keep Alive Monitor Agent Core DPDK core is required
+to detect its failure.
+
+Note: This application is based on the L2 forwarding application. As
+such, the initialization and run-time paths are very similar to those
+of the L2 forwarding application.
+
+Compiling the Application
+-------------------------
+
+To compile the application:
+
+#.  Go to the sample application directory:
+
+    .. code-block:: console
+
+        export RTE_SDK=/path/to/rte_sdk cd ${RTE_SDK}/examples/keep_alive
+
+#.  Set the target (a default target is used if not specified). For example:
+
+    .. code-block:: console
+
+        export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+    See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+
+#.  Build the application:
+
+    .. code-block:: console
+
+        make
+
+Running the Application
+-----------------------
+
+The application has a number of command line options:
+
+.. code-block:: console
+
+    ./build/l2fwd-keepalive [EAL options] \
+            -- -p PORTMASK [-q NQ] [-K PERIOD] [-T PERIOD]
+
+where,
+
+* ``p PORTMASK``: A hexadecimal bitmask of the ports to configure
+
+* ``q NQ``: A number of queues (=ports) per lcore (default is 1)
+
+* ``K PERIOD``: Heartbeat check period in ms(5ms default; 86400 max)
+
+* ``T PERIOD``: statistics will be refreshed each PERIOD seconds (0 to
+  disable, 10 default, 86400 maximum).
+
+To run the application in linuxapp environment with 4 lcores, 16 ports
+8 RX queues per lcore and a ping interval of 10ms, issue the command:
+
+.. code-block:: console
+
+    ./build/l2fwd-keepalive -c f -n 4 -- -q 8 -p ffff -K 10
+
+Refer to the *DPDK Getting Started Guide* for general information on
+running applications and the Environment Abstraction Layer (EAL)
+options.
+
+
+Explanation
+-----------
+
+The following sections provide some explanation of the The
+Keep-Alive/'Liveliness' conceptual scheme. As mentioned in the
+overview section, the initialization and run-time paths are very
+similar to those of the L2 forwarding application (see Chapter 9
+"L2 Forwarding Sample Application (in Real and Virtualized
+Environments)" for more information).
+
+The Keep-Alive/'Liveliness' conceptual scheme:
+
+* A Keep- Alive Agent Runs every N Milliseconds.
+
+* DPDK Cores respond to the keep-alive agent.
+
+* If keep-alive agent detects time-outs, it notifies the
+  fault management entity through a callback function.
+
+The following sections provide some explanation of the code aspects
+that are specific to the Keep Alive sample application.
+
+The heartbeat functionality is initialized with a struct
+rte_heartbeat and the callback function to invoke in the
+case of a timeout.
+
+.. code-block:: c
+
+    rte_global_keepalive_info = rte_keepalive_create(&dead_core, NULL);
+    if (rte_global_hbeat_info == NULL)
+        rte_exit(EXIT_FAILURE, "keepalive_create() failed");
+
+The function that issues the pings hbeat_dispatch_pings()
+is configured to run every check_period milliseconds.
+
+.. code-block:: c
+
+    if (rte_timer_reset(&hb_timer,
+            (check_period * rte_get_timer_hz()) / 1000,
+            PERIODICAL,
+            rte_lcore_id(),
+            &hbeat_dispatch_pings, rte_global_keepalive_info
+            ) != 0 )
+        rte_exit(EXIT_FAILURE, "Keepalive setup failure.\n");
+
+The rest of the initialization and run-time path follows
+the same paths as the the L2 forwarding application. The only
+addition to the main processing loop is the mark alive
+functionality and the example random failures.
+
+.. code-block:: c
+
+    rte_keepalive_mark_alive(&rte_global_hbeat_info);
+    cur_tsc = rte_rdtsc();
+
+    /* Die randomly within 7 secs for demo purposes.. */
+    if (cur_tsc - tsc_initial > tsc_lifetime)
+    break;
+
+The rte_keepalive_mark_alive function simply sets the core state to alive.
+
+.. code-block:: c
+
+    static inline void
+    rte_keepalive_mark_alive(struct rte_heartbeat *keepcfg)
+    {
+        keepcfg->state_flags[rte_lcore_id()] = 1;
+    }

Looks good in general, just few small things, see below.
Thanks

I think it actually depends only on these two:
http://dpdk.org/dev/patchwork/patch/6563/
http://dpdk.org/dev/patchwork/patch/8070/

1) From [PATCH v3 1/2] example: add user-space ethtool sample application

+int main(int argc, char **argv)
+{
+	int cnt_args_parsed;
+	uint32_t idx_port;
+	uint32_t id_core;
+	uint32_t cnt_ports;
+	struct app_port *ptr_port;
+
+	/* Init runtime enviornment */
+	cnt_args_parsed = rte_eal_init(argc, argv);
+	if (cnt_args_parsed < 0)
+		rte_exit(EXIT_FAILURE, "rte_eal_init(): Failed");
+
+	cnt_ports = rte_eth_dev_count();
+	printf("Eth NICs: %i\n", cnt_ports);
+	if (cnt_ports > MAX_PORTS) {
+		printf("Info: Using only %i of %i ports\n",
+			cnt_ports, MAX_PORTS
+			);
+		cnt_ports = MAX_PORTS;
+	}
+
+	setup_ports(&app_cfg, cnt_ports);
+
+	id_core = rte_lcore_id();
+	for (idx_port = 0; idx_port < cnt_ports; idx_port++) {
+		id_core = rte_get_next_lcore(id_core, 1, 0);
+		if (id_core == RTE_MAX_LCORE) {
+			printf("Warning: More ports than cores. "
+				"Some ports will not be active.\n");
+			break;
+		}

Master core is not always the first active core.
User can select a master lcore with '--master-lcore X' command-line option.
Another thing - why do you need a separate lcore for each port?
It means that if user would like to test X different ports he/she would need X+1 lcores to run the app.
I understand that you are trying to keep the app as simple as possible, but why not visa-versa then?
Make all ports managed by one slave lcore?
It might slowdown things as number of ports grow, but from other side this app is
mainly for functional testing of ethtool shim layer, so I think it is not a problem.

+		ptr_port = &app_cfg.ports[idx_port];
+		rte_eal_remote_launch(slave_main, ptr_port, id_core);
+	}
+
+	ethapp_main();
+
+	for (idx_port = 0; idx_port < cnt_ports; idx_port++)
+		app_cfg.ports[idx_port].exit_now = 1;
+	RTE_LCORE_FOREACH_SLAVE(id_core) {
+		if (rte_eal_wait_lcore(id_core) < 0)
+			return -1;
+	}
+
+	return 0;
+}

2) From: [PATCH v3 2/2] doc: add user-space ethtool sample app guide

It looks like a guide for keep-alive not ehttool :)

[PATCH v4 0/2] User-space ethtool sample application

[Remy Horton]

Further enhancements to the userspace ethtool implementation that was
submitted in 2.1 and packaged as a self-contained sample application.
Implements an rte_ethtool shim layer based on rte_ethdev API, along
with a command prompt driven demonstration application.

This patchset depends on:
* http://dpdk.org/dev/patchwork/patch/6563/
* http://dpdk.org/dev/patchwork/patch/8070/

v4:
* Fixed assumption that master core always has id zero
* Changed 1:1 core-to-port to 2 core (ethtool & ports) design 
* Included the correct documentation..

v3:
* Made use of enums for core state.
* Fixed Makefile issue.
* Fixed incorrect assumption with core ids.
* Changed handling of more ports than cores.

v2:
* Replaced l2fwd base with simpler application.
* Added ringparam functions.
* Added documentation.

+
+EthTool Sample Application
+==========================
+
+The Ethtool sample application shows an implementation of an
+EthTool-like API and provides a console environment that allows
+its use to query and change Ethernet card parameters. The sample
+is based upon a simple L2 frame reflector.
+
+
+Compiling the Application
+-------------------------
+
+To compile the application:
+
+#.  Go to the sample application directory:
+
+    .. code-block:: console
+
+        export RTE_SDK=/path/to/rte_sdk cd ${RTE_SD}/examples/ethtool
+
+#.  Set the target (a default target is used if not specified). For example:
+
+    .. code-block:: console
+
+        export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+    See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+
+#.  Build the application:
+
+    .. code-block:: console
+
+        make
+
+Running the Application
+-----------------------
+
+The application requires an available core for each port, plus one.
+The only available options are the standard ones for the EAL:
+
+.. code-block:: console
+
+    ./build/ethtool [EAL options]
+
+Refer to the *DPDK Getting Started Guide* for general information on
+running applications and the Environment Abstraction Layer (EAL)
+options.
+
+Using the application
+---------------------
+
+The application is console-driven using the cmdline DPDK interface:
+
+.. code-block:: console
+
+        EthApp>
+
+From this interface the available commands and descriptions of what
+they do as as follows:
+
+drvinfo
+        Print driver info
+eeprom
+        Dump EEPROM to file
+link
+        Print port link states
+macaddr
+        Gets/sets MAC address
+mtu
+        Set NIC MTU
+open
+        Open port
+pause
+        Get/set port pause state
+portstats
+        Print port statistics
+regs
+        Dump port register(s) to file
+ringparam
+        Get/set ring parameters
+rxmode
+        Toggle port Rx mode
+stop
+        Stop port
+validate
+        Check that given MAC address is valid unicast address
+vlan
+        Add/remove VLAN id
+quit
+        Exit program
+
+
+Explaination
+------------
+
+The following sections describe the most important parts of the code.
+
+
+Base program
+~~~~~~~~~~~~
+
+The top-level, after some port initialisation routines, runs the following:
+
+.. code-block:: c
+
+	for (idx_port = 0; idx_port < cnt_ports; idx_port++) {
+		ptr_port = &app_cfg.ports[idx_port];
+		rte_eal_remote_launch(slave_main, ptr_port, idx_port + 1);

+	ethapp_main();
+
+Each slave core, or a subset of these cores if there are more cores then
+NIC ports, runs the `slave core process`_ described below. The master core
+then runs the `EthTool App`_ itself.
+
+
+Slave core process
+~~~~~~~~~~~~~~~~~~
+
+Each slave core is assigned one of the available ports, and runs
+the following code that implements a simple MAC frame refector:
+
+.. code-block:: c
+
+	while (!ptr_port->exit_now) {
+		rte_spinlock_lock(&ptr_port->lock);
+		if (ptr_port->port_active == 0 ) {
+			rte_spinlock_unlock(&ptr_port->lock);
+			continue;
+		}
+
+		/* Incoming frames */
+		cnt_backlog_frames = ptr_txq->cnt_frames;
+		cnt_recv_frames = rte_eth_rx_burst(
+			ptr_port->idx_port, 0,
+			&buf_recv_frames[ptr_txq->cnt_frames],
+			MAX_BURST_LENGTH - cnt_backlog_frames
+			);
+		if (cnt_recv_frames > 0) {
+			for (idx_frame = 0;
+					idx_frame < cnt_recv_frames;
+					idx_frame++) {
+				ptr_frame = buf_recv_frames[
+					idx_frame + cnt_backlog_frames];
+				process_frame(ptr_port, ptr_frame);
+			}
+		}
+
+		/* Outgoing frames */
+		if (ptr_txq->cnt_frames > 0) {
+			cnt_sent = rte_eth_tx_burst(
+				ptr_port->idx_port, 0,
+				ptr_txq->ptr_frames,
+				ptr_txq->cnt_frames
+				);
+			/* Shuffle up unsent frame pointers */
+			for (idx_frame = cnt_sent;
+					idx_frame < ptr_txq->cnt_frames;
+					idx_frame++)
+				ptr_txq->ptr_frames[idx_frame - cnt_sent] =
+					ptr_txq->ptr_frames[idx_frame];
+			ptr_txq->cnt_frames -= cnt_sent;
+		}
+		rte_spinlock_unlock(&ptr_port->lock);
+
+	} /* end for(;;) */
+
+There is a check to make sure the port is in an active state. A burst
+of frames is read and each frame within this burst is processed as
+described below. Outgoing frames are then dispatched as a single burst,
+with unsent frames being shuffled to the front of the outgoing queue if
+not all of the frames could be sent.
+
+The processing of individial frames consists of setting the destination
+address to be the source address, setting the source address to be the
+MAC address of the port being handled, and then queueing the frame for
+transmission:
+
+.. code-block:: c
+
+	ptr_mac_hdr = rte_pktmbuf_mtod(ptr_frame, struct ether_hdr *);
+	ether_addr_copy(&ptr_mac_hdr->s_addr, &ptr_mac_hdr->d_addr);
+	rte_eth_macaddr_get(ptr_port->idx_port, &ptr_mac_hdr->s_addr);
+	ptr_port->tx_queue.ptr_frames[ptr_port->tx_queue.cnt_frames++] =
+		ptr_frame;
+
+
+EthTool App
+~~~~~~~~~~~
+
+The ``foreground`` part of the EthTool sample is a console-based
+interface that accepts commands as described in `using the
+application`_.
+
+.. code-block:: c
+
+	ctx_cmdline = cmdline_stdin_new(list_prompt_commands, "EthApp> ");
+	cmdline_interact(ctx_cmdline);
+	cmdline_stdin_exit(ctx_cmdline);
+
+
+Individual call-back functions handle the detail associated with each
+command, which make use of the functions defined in the `EthTool interface`_
+to the DPDK functions.
+
+
+EthTool interface
+~~~~~~~~~~~~~~~~~
+
+The EthTool interface is built as a separate library, and implements
+the following functions:
+
+- rte_ethtool_get_drvinfo

[PATCH v5 0/2] User-space ethtool sample application

[Remy Horton]

Further enhancements to the userspace ethtool implementation that was
submitted in 2.1 and packaged as a self-contained sample application.
Implements an rte_ethtool shim layer based on rte_ethdev API, along
with a command prompt driven demonstration application.

This patchset depends on:
* http://dpdk.org/dev/patchwork/patch/6563/
* http://dpdk.org/dev/patchwork/patch/8070/

v5:
* Documentation changes

v4:
* Fixed assumption that master core always has id zero
* Changed 1:1 core-to-port to 2 core (ethtool & ports) design 
* Included the correct documentation..

v3:
* Made use of enums for core state.
* Fixed Makefile issue.
* Fixed incorrect assumption with core ids.
* Changed handling of more ports than cores.

v2:
* Replaced l2fwd base with simpler application.
* Added ringparam functions.
* Added documentation.

+
+EthTool Sample Application
+==========================
+
+The Ethtool sample application shows an implementation of an
+EthTool-like API and provides a console environment that allows
+its use to query and change Ethernet card parameters. The sample
+is based upon a simple L2 frame reflector.
+
+Compiling the Application
+-------------------------
+
+To compile the application:
+
+#.  Go to the sample application directory:
+
+    .. code-block:: console
+
+        export RTE_SDK=/path/to/rte_sdk cd ${RTE_SD}/examples/ethtool
+
+#.  Set the target (a default target is used if not specified). For example:
+
+    .. code-block:: console
+
+        export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+    See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+
+#.  Build the application:
+
+    .. code-block:: console
+
+        make
+
+Running the Application
+-----------------------
+
+The application requires an available core for each port, plus one.
+The only available options are the standard ones for the EAL:
+
+.. code-block:: console
+
+    ./ethtool-app/ethtool-app/${RTE_TARGET}/ethtool [EAL options]
+
+Refer to the *DPDK Getting Started Guide* for general information on
+running applications and the Environment Abstraction Layer (EAL)
+options.
+
+Using the application
+---------------------
+
+The application is console-driven using the cmdline DPDK interface:
+
+.. code-block:: console
+
+        EthApp>
+
+From this interface the available commands and descriptions of what
+they do as as follows:
+
+drvinfo
+        Print driver info
+eeprom
+        Dump EEPROM to file

+Explaination
+------------
+
+The sample program has two parts: A background `packet reflector`_
+that runs on a slave core, and a foreground `EthTool Shell`_ that
+runs on the master core. These are described below.
+
+Packet Reflector
+~~~~~~~~~~~~~~~~
+
+The background packet reflector is intended to demonstrate basic
+packet processing on NIC ports controlled by the EthTool shim.
+Each incoming MAC frame is rewritten so that it is returned to
+the sender, using the port in question's own MAC address as the
+source address, and is then sent out on the same port.
+
+EthTool Shell
+~~~~~~~~~~~~~
+
+The foreground part of the EthTool sample is a console-based
+interface that accepts commands as described in `using the
+application`_. Individual call-back functions handle the detail
+associated with each command, which make use of the functions
+defined in the `EthTool interface`_ to the DPDK functions.
+
+EthTool interface
+-----------------
+
+The EthTool interface is built as a separate library, and implements
+the following functions:
+
+- rte_ethtool_get_drvinfo
+- rte_ethtool_get_regs_len
+- rte_ethtool_get_regs
+- rte_ethtool_get_link
+- rte_ethtool_get_eeprom_len
+- rte_ethtool_get_eeprom
+- rte_ethtool_set_eeprom
+- rte_ethtool_get_pauseparam
+- rte_ethtool_set_pauseparam
+- rte_ethtool_net_open
+- rte_ethtool_net_stop
+- rte_ethtool_net_get_mac_addr
+- rte_ethtool_net_set_mac_addr
+- rte_ethtool_net_validate_addr
+- rte_ethtool_net_change_mtu
+- rte_ethtool_net_get_stats64

[PATCH v6 0/2] User-space ethtool sample application

[Remy Horton]

Further enhancements to the userspace ethtool implementation that was
submitted in 2.1 and packaged as a self-contained sample application.
Implements an rte_ethtool shim layer based on rte_ethdev API, along
with a command prompt driven demonstration application.

This patchset depends on:
* http://dpdk.org/dev/patchwork/patch/6563/
* http://dpdk.org/dev/patchwork/patch/8070/

v6:
* Fixed hang when run with zero available ports
* Fixed incorrect sanity check preventing EEPROM dumps
* Documentation additions
* Fixed RxMode accepting untagged packets
* Fixed ringparam allocation being too small

v5:
* Documentation changes

v4:
* Fixed assumption that master core always has id zero
* Changed 1:1 core-to-port to 2 core (ethtool & ports) design 
* Included the correct documentation..

v3:
* Made use of enums for core state.
* Fixed Makefile issue.
* Fixed incorrect assumption with core ids.
* Changed handling of more ports than cores.

v2:
* Replaced l2fwd base with simpler application.
* Added ringparam functions.
* Added documentation.

+EthTool Sample Application
+==========================
+
+The Ethtool sample application shows an implementation of an
+EthTool-like API and provides a console environment that allows
+its use to query and change Ethernet card parameters. The sample
+is based upon a simple L2 frame reflector.
+
+Compiling the Application
+-------------------------
+
+To compile the application:
+
+#.  Go to the sample application directory:
+
+    .. code-block:: console
+
+        export RTE_SDK=/path/to/rte_sdk cd ${RTE_SD}/examples/ethtool
+
+#.  Set the target (a default target is used if not specified). For example:
+
+    .. code-block:: console
+
+        export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+    See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+
+#.  Build the application:
+
+    .. code-block:: console
+
+        make
+
+Running the Application
+-----------------------
+
+The application requires an available core for each port, plus one.
+The only available options are the standard ones for the EAL:
+
+.. code-block:: console
+
+    ./ethtool-app/ethtool-app/${RTE_TARGET}/ethtool [EAL options]
+
+Refer to the *DPDK Getting Started Guide* for general information on
+running applications and the Environment Abstraction Layer (EAL)
+options.
+
+Using the application
+---------------------
+
+The application is console-driven using the cmdline DPDK interface:
+
+.. code-block:: console
+
+        EthApp>
+
+From this interface the available commands and descriptions of what
+they do as as follows:
+
+drvinfo
+        Print driver info
+eeprom
+        Dump EEPROM to file
+link
+        Print port link states
+macaddr
+        Gets/sets MAC address
+mtu
+        Set NIC MTU
+open
+        Open port
+pause
+        Get/set port pause state
+portstats
+        Print port statistics
+regs
+        Dump port register(s) to file
+ringparam
+        Get/set ring parameters
+rxmode
+        Toggle port Rx mode
+stop
+        Stop port
+validate
+        Check that given MAC address is valid unicast address
+vlan
+        Add/remove VLAN id
+quit
+        Exit program
+
+Explaination
+------------
+
+The sample program has two parts: A background `packet reflector`_
+that runs on a slave core, and a foreground `EthTool Shell`_ that
+runs on the master core. These are described below.
+
+Packet Reflector
+~~~~~~~~~~~~~~~~
+
+The background packet reflector is intended to demonstrate basic
+packet processing on NIC ports controlled by the EthTool shim.
+Each incoming MAC frame is rewritten so that it is returned to
+the sender, using the port in question's own MAC address as the
+source address, and is then sent out on the same port.
+
+EthTool Shell
+~~~~~~~~~~~~~
+
+The foreground part of the EthTool sample is a console-based
+interface that accepts commands as described in `using the
+application`_. Individual call-back functions handle the detail
+associated with each command, which make use of the functions
+defined in the `EthTool interface`_ to the DPDK functions.
+
+EthTool interface
+-----------------
+
+The EthTool interface is built as a separate library, and implements
+the following functions:
+
+- rte_ethtool_get_drvinfo
+- rte_ethtool_get_regs_len
+- rte_ethtool_get_regs
+- rte_ethtool_get_link
+- rte_ethtool_get_eeprom_len

Hi,

Thanks for this. A few minor comments below:

In some place the app is called EthTool and in some Ethtool. Use one or the other.

Although "EthTool-like" should probably be "ethtool-like" since it is like "ethtool"
and that is usually written in lowercase.

Split the two commands onto two lines.

This definition list doesn't render very well. Maybe better as:

* ``drvinfo``: Print driver info.
* ``eeprom``: Dump EEPROM to file.
* ``link``: Print port link states.
* ``macaddr``: Gets/sets MAC address.
* ``mtu``: Set NIC MTU.
* ``open``: Open port.
* ``pause``: Get/set port pause state.
* ``portstats``: Print port statistics.
* ``regs``: Dump port register(s) to file.
* ``ringparam``: Get/set ring parameters.
* ``rxmode``: Toggle port Rx mode.
* ``stop``: Stop port.
* ``validate``: Check that given MAC address is valid unicast address.
* ``vlan``: Add/remove VLAN id.
* ``quit``: Exit program.

Maybe better as fixed width text:

- ``rte_ethtool_get_drvinfo()``
- ``rte_ethtool_get_regs_len()``
- ``rte_ethtool_get_regs()``
- ``rte_ethtool_get_link()``

Ideally would present it as a table, but stylistically that felt too 
different from the rest of the documentation. Gone with bullet list.

Will roll the changes into the next patchset.

+
+Ethtool Sample Application
+==========================
+
+The Ethtool sample application shows an implementation of an
+ethtool-like API and provides a console environment that allows
+its use to query and change Ethernet card parameters. The sample
+is based upon a simple L2 frame reflector.
+
+Compiling the Application
+-------------------------
+
+To compile the application:
+
+#.  Go to the sample application directory:
+
+    .. code-block:: console
+
+        export RTE_SDK=/path/to/rte_sdk
+        cd ${RTE_SD}/examples/ethtool
+
+#.  Set the target (a default target is used if not specified). For example:
+
+    .. code-block:: console
+
+        export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+    See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+
+#.  Build the application:
+
+    .. code-block:: console
+
+        make
+
+Running the Application
+-----------------------
+
+The application requires an available core for each port, plus one.
+The only available options are the standard ones for the EAL:
+
+.. code-block:: console
+
+    ./ethtool-app/ethtool-app/${RTE_TARGET}/ethtool [EAL options]
+
+Refer to the *DPDK Getting Started Guide* for general information on
+running applications and the Environment Abstraction Layer (EAL)
+options.
+
+Using the application
+---------------------
+
+The application is console-driven using the cmdline DPDK interface:
+
+.. code-block:: console
+
+        EthApp>
+
+From this interface the available commands and descriptions of what
+they do as as follows:
+
+* ``drvinfo``: Print driver info
+* ``eeprom``: Dump EEPROM to file
+* ``link``: Print port link states
+* ``macaddr``: Gets/sets MAC address
+* ``mtu``: Set NIC MTU
+* ``open``: Open port
+* ``pause``: Get/set port pause state
+* ``portstats``: Print port statistics
+* ``regs``: Dump port register(s) to file
+* ``ringparam``: Get/set ring parameters
+* ``rxmode``: Toggle port Rx mode
+* ``stop``: Stop port
+* ``validate``: Check that given MAC address is valid unicast address
+* ``vlan``: Add/remove VLAN id
+* ``quit``: Exit program
+
+
+Explanation
+-----------
+
+The sample program has two parts: A background `packet reflector`_
+that runs on a slave core, and a foreground `Ethtool Shell`_ that
+runs on the master core. These are described below.
+
+Packet Reflector
+~~~~~~~~~~~~~~~~
+
+The background packet reflector is intended to demonstrate basic
+packet processing on NIC ports controlled by the Ethtool shim.
+Each incoming MAC frame is rewritten so that it is returned to
+the sender, using the port in question's own MAC address as the
+source address, and is then sent out on the same port.
+
+Ethtool Shell
+~~~~~~~~~~~~~
+
+The foreground part of the Ethtool sample is a console-based
+interface that accepts commands as described in `using the
+application`_. Individual call-back functions handle the detail
+associated with each command, which make use of the functions
+defined in the `Ethtool interface`_ to the DPDK functions.
+
+Ethtool interface
+-----------------
+
+The Ethtool interface is built as a separate library, and implements
+the following functions:
+
+- ``rte_ethtool_get_drvinfo()``
+- ``rte_ethtool_get_regs_len()``
+- ``rte_ethtool_get_regs()``
+- ``rte_ethtool_get_link()``
+- ``rte_ethtool_get_eeprom_len()``
+- ``rte_ethtool_get_eeprom()``
+- ``rte_ethtool_set_eeprom()``
+- ``rte_ethtool_get_pauseparam()``
+- ``rte_ethtool_set_pauseparam()``
+- ``rte_ethtool_net_open()``
+- ``rte_ethtool_net_stop()``
+- ``rte_ethtool_net_get_mac_addr()``
+- ``rte_ethtool_net_set_mac_addr()``
+- ``rte_ethtool_net_validate_addr()``
+- ``rte_ethtool_net_change_mtu()``
+- ``rte_ethtool_net_get_stats64()``
+- ``rte_ethtool_net_vlan_rx_add_vid()``
+- ``rte_ethtool_net_vlan_rx_kill_vid()``
+- ``rte_ethtool_net_set_rx_mode()``
+- ``rte_ethtool_get_ringparam()``
+- ``rte_ethtool_set_ringparam()``

[PATCH v8 0/2] User-space ethtool sample application

[Remy Horton]

Further enhancements to the userspace ethtool implementation that was
submitted in 2.1 and packaged as a self-contained sample application.
Implements an rte_ethtool shim layer based on rte_ethdev API, along
with a command prompt driven demonstration application.

This patchset depends on:
* http://dpdk.org/dev/patchwork/patch/6563/
* http://dpdk.org/dev/patchwork/patch/8070/

v8:
* Rebased to latest origin/master

v7:
* Ringparam printouts wrong way round
* Ringparam help message corrections
* Use __rte_unused instead of __attribute__((unused))
* Allow Jumbo-sized MTUs
* Documentation style and spelling changes

v6:
* Fixed hang when run with zero available ports
* Fixed incorrect sanity check preventing EEPROM dumps
* Documentation additions
* Fixed RxMode accepting untagged packets
* Fixed ringparam allocation being too small

v5:
* Documentation changes

v4:
* Fixed assumption that master core always has id zero
* Changed 1:1 core-to-port to 2 core (ethtool & ports) design 
* Included the correct documentation..

v3:
* Made use of enums for core state.
* Fixed Makefile issue.
* Fixed incorrect assumption with core ids.
* Changed handling of more ports than cores.

v2:
* Replaced l2fwd base with simpler application.
* Added ringparam functions.
* Added documentation.

+
+Ethtool Sample Application
+==========================
+
+The Ethtool sample application shows an implementation of an
+ethtool-like API and provides a console environment that allows
+its use to query and change Ethernet card parameters. The sample
+is based upon a simple L2 frame reflector.
+
+Compiling the Application
+-------------------------
+
+To compile the application:
+
+#.  Go to the sample application directory:
+
+    .. code-block:: console
+
+        export RTE_SDK=/path/to/rte_sdk
+        cd ${RTE_SD}/examples/ethtool
+
+#.  Set the target (a default target is used if not specified). For example:
+
+    .. code-block:: console
+
+        export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+    See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+
+#.  Build the application:
+
+    .. code-block:: console
+
+        make
+
+Running the Application
+-----------------------
+
+The application requires an available core for each port, plus one.
+The only available options are the standard ones for the EAL:
+
+.. code-block:: console
+
+    ./ethtool-app/ethtool-app/${RTE_TARGET}/ethtool [EAL options]
+
+Refer to the *DPDK Getting Started Guide* for general information on
+running applications and the Environment Abstraction Layer (EAL)
+options.
+
+Using the application
+---------------------
+
+The application is console-driven using the cmdline DPDK interface:
+
+.. code-block:: console
+
+        EthApp>
+
+From this interface the available commands and descriptions of what
+they do as as follows:
+
+* ``drvinfo``: Print driver info
+* ``eeprom``: Dump EEPROM to file
+* ``link``: Print port link states
+* ``macaddr``: Gets/sets MAC address
+* ``mtu``: Set NIC MTU
+* ``open``: Open port
+* ``pause``: Get/set port pause state
+* ``portstats``: Print port statistics
+* ``regs``: Dump port register(s) to file
+* ``ringparam``: Get/set ring parameters
+* ``rxmode``: Toggle port Rx mode
+* ``stop``: Stop port
+* ``validate``: Check that given MAC address is valid unicast address
+* ``vlan``: Add/remove VLAN id
+* ``quit``: Exit program
+
+
+Explanation
+-----------
+
+The sample program has two parts: A background `packet reflector`_
+that runs on a slave core, and a foreground `Ethtool Shell`_ that
+runs on the master core. These are described below.
+
+Packet Reflector
+~~~~~~~~~~~~~~~~
+
+The background packet reflector is intended to demonstrate basic
+packet processing on NIC ports controlled by the Ethtool shim.
+Each incoming MAC frame is rewritten so that it is returned to
+the sender, using the port in question's own MAC address as the
+source address, and is then sent out on the same port.
+
+Ethtool Shell
+~~~~~~~~~~~~~
+
+The foreground part of the Ethtool sample is a console-based
+interface that accepts commands as described in `using the
+application`_. Individual call-back functions handle the detail
+associated with each command, which make use of the functions
+defined in the `Ethtool interface`_ to the DPDK functions.
+
+Ethtool interface
+-----------------
+
+The Ethtool interface is built as a separate library, and implements
+the following functions:
+
+- ``rte_ethtool_get_drvinfo()``
+- ``rte_ethtool_get_regs_len()``
+- ``rte_ethtool_get_regs()``
+- ``rte_ethtool_get_link()``
+- ``rte_ethtool_get_eeprom_len()``
+- ``rte_ethtool_get_eeprom()``
+- ``rte_ethtool_set_eeprom()``
+- ``rte_ethtool_get_pauseparam()``
+- ``rte_ethtool_set_pauseparam()``
+- ``rte_ethtool_net_open()``
+- ``rte_ethtool_net_stop()``
+- ``rte_ethtool_net_get_mac_addr()``
+- ``rte_ethtool_net_set_mac_addr()``
+- ``rte_ethtool_net_validate_addr()``
+- ``rte_ethtool_net_change_mtu()``
+- ``rte_ethtool_net_get_stats64()``
+- ``rte_ethtool_net_vlan_rx_add_vid()``
+- ``rte_ethtool_net_vlan_rx_kill_vid()``
+- ``rte_ethtool_net_set_rx_mode()``
+- ``rte_ethtool_get_ringparam()``
+- ``rte_ethtool_set_ringparam()``

I'm really sorry, it doesn't compile in combined library mode.
We have to check it very shortly.

Looks like rte.extlib.mk not making the sub-directories that combined 
builds use. Whole patch needs rebasing anyway due to a merge conflict so 
will fix that as well..

+
+Ethtool Sample Application
+==========================
+
+The Ethtool sample application shows an implementation of an
+ethtool-like API and provides a console environment that allows
+its use to query and change Ethernet card parameters. The sample
+is based upon a simple L2 frame reflector.
+
+Compiling the Application
+-------------------------
+
+To compile the application:
+
+#.  Go to the sample application directory:
+
+    .. code-block:: console
+
+        export RTE_SDK=/path/to/rte_sdk
+        cd ${RTE_SD}/examples/ethtool
+
+#.  Set the target (a default target is used if not specified). For example:
+
+    .. code-block:: console
+
+        export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+    See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+
+#.  Build the application:
+
+    .. code-block:: console
+
+        make
+
+Running the Application
+-----------------------
+
+The application requires an available core for each port, plus one.
+The only available options are the standard ones for the EAL:
+
+.. code-block:: console
+
+    ./ethtool-app/ethtool-app/${RTE_TARGET}/ethtool [EAL options]
+
+Refer to the *DPDK Getting Started Guide* for general information on
+running applications and the Environment Abstraction Layer (EAL)
+options.
+
+Using the application
+---------------------
+
+The application is console-driven using the cmdline DPDK interface:
+
+.. code-block:: console
+
+        EthApp>
+
+From this interface the available commands and descriptions of what
+they do as as follows:
+
+* ``drvinfo``: Print driver info
+* ``eeprom``: Dump EEPROM to file
+* ``link``: Print port link states
+* ``macaddr``: Gets/sets MAC address
+* ``mtu``: Set NIC MTU
+* ``open``: Open port
+* ``pause``: Get/set port pause state
+* ``portstats``: Print port statistics
+* ``regs``: Dump port register(s) to file
+* ``ringparam``: Get/set ring parameters
+* ``rxmode``: Toggle port Rx mode
+* ``stop``: Stop port
+* ``validate``: Check that given MAC address is valid unicast address
+* ``vlan``: Add/remove VLAN id
+* ``quit``: Exit program
+
+
+Explanation
+-----------
+
+The sample program has two parts: A background `packet reflector`_
+that runs on a slave core, and a foreground `Ethtool Shell`_ that
+runs on the master core. These are described below.
+
+Packet Reflector
+~~~~~~~~~~~~~~~~
+
+The background packet reflector is intended to demonstrate basic
+packet processing on NIC ports controlled by the Ethtool shim.
+Each incoming MAC frame is rewritten so that it is returned to
+the sender, using the port in question's own MAC address as the
+source address, and is then sent out on the same port.
+
+Ethtool Shell
+~~~~~~~~~~~~~
+
+The foreground part of the Ethtool sample is a console-based
+interface that accepts commands as described in `using the
+application`_. Individual call-back functions handle the detail
+associated with each command, which make use of the functions
+defined in the `Ethtool interface`_ to the DPDK functions.
+
+Ethtool interface
+-----------------
+
+The Ethtool interface is built as a separate library, and implements
+the following functions:
+
+- ``rte_ethtool_get_drvinfo()``
+- ``rte_ethtool_get_regs_len()``
+- ``rte_ethtool_get_regs()``
+- ``rte_ethtool_get_link()``
+- ``rte_ethtool_get_eeprom_len()``
+- ``rte_ethtool_get_eeprom()``
+- ``rte_ethtool_set_eeprom()``
+- ``rte_ethtool_get_pauseparam()``
+- ``rte_ethtool_set_pauseparam()``
+- ``rte_ethtool_net_open()``
+- ``rte_ethtool_net_stop()``
+- ``rte_ethtool_net_get_mac_addr()``
+- ``rte_ethtool_net_set_mac_addr()``
+- ``rte_ethtool_net_validate_addr()``
+- ``rte_ethtool_net_change_mtu()``
+- ``rte_ethtool_net_get_stats64()``
+- ``rte_ethtool_net_vlan_rx_add_vid()``
+- ``rte_ethtool_net_vlan_rx_kill_vid()``
+- ``rte_ethtool_net_set_rx_mode()``
+- ``rte_ethtool_get_ringparam()``
+- ``rte_ethtool_set_ringparam()``

+
+Ethtool Sample Application
+==========================
+
+The Ethtool sample application shows an implementation of an
+ethtool-like API and provides a console environment that allows
+its use to query and change Ethernet card parameters. The sample
+is based upon a simple L2 frame reflector.
+
+Compiling the Application
+-------------------------
+
+To compile the application:
+
+#.  Go to the sample application directory:
+
+    .. code-block:: console
+
+        export RTE_SDK=/path/to/rte_sdk
+        cd ${RTE_SD}/examples/ethtool
+
+#.  Set the target (a default target is used if not specified). For example:
+
+    .. code-block:: console
+
+        export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+    See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+
+#.  Build the application:
+
+    .. code-block:: console
+
+        make
+
+Running the Application
+-----------------------
+
+The application requires an available core for each port, plus one.
+The only available options are the standard ones for the EAL:
+
+.. code-block:: console
+
+    ./ethtool-app/ethtool-app/${RTE_TARGET}/ethtool [EAL options]
+
+Refer to the *DPDK Getting Started Guide* for general information on
+running applications and the Environment Abstraction Layer (EAL)
+options.
+
+Using the application
+---------------------
+
+The application is console-driven using the cmdline DPDK interface:
+
+.. code-block:: console
+
+        EthApp>
+
+From this interface the available commands and descriptions of what
+they do as as follows:
+
+* ``drvinfo``: Print driver info
+* ``eeprom``: Dump EEPROM to file
+* ``link``: Print port link states
+* ``macaddr``: Gets/sets MAC address
+* ``mtu``: Set NIC MTU
+* ``open``: Open port
+* ``pause``: Get/set port pause state
+* ``portstats``: Print port statistics
+* ``regs``: Dump port register(s) to file
+* ``ringparam``: Get/set ring parameters
+* ``rxmode``: Toggle port Rx mode
+* ``stop``: Stop port
+* ``validate``: Check that given MAC address is valid unicast address
+* ``vlan``: Add/remove VLAN id
+* ``quit``: Exit program
+
+
+Explanation
+-----------
+
+The sample program has two parts: A background `packet reflector`_
+that runs on a slave core, and a foreground `Ethtool Shell`_ that
+runs on the master core. These are described below.
+
+Packet Reflector
+~~~~~~~~~~~~~~~~
+
+The background packet reflector is intended to demonstrate basic
+packet processing on NIC ports controlled by the Ethtool shim.
+Each incoming MAC frame is rewritten so that it is returned to
+the sender, using the port in question's own MAC address as the
+source address, and is then sent out on the same port.
+
+Ethtool Shell
+~~~~~~~~~~~~~
+
+The foreground part of the Ethtool sample is a console-based
+interface that accepts commands as described in `using the
+application`_. Individual call-back functions handle the detail
+associated with each command, which make use of the functions
+defined in the `Ethtool interface`_ to the DPDK functions.
+
+Ethtool interface
+-----------------
+
+The Ethtool interface is built as a separate library, and implements
+the following functions:
+
+- ``rte_ethtool_get_drvinfo()``
+- ``rte_ethtool_get_regs_len()``
+- ``rte_ethtool_get_regs()``
+- ``rte_ethtool_get_link()``
+- ``rte_ethtool_get_eeprom_len()``
+- ``rte_ethtool_get_eeprom()``
+- ``rte_ethtool_set_eeprom()``
+- ``rte_ethtool_get_pauseparam()``
+- ``rte_ethtool_set_pauseparam()``
+- ``rte_ethtool_net_open()``
+- ``rte_ethtool_net_stop()``
+- ``rte_ethtool_net_get_mac_addr()``
+- ``rte_ethtool_net_set_mac_addr()``
+- ``rte_ethtool_net_validate_addr()``
+- ``rte_ethtool_net_change_mtu()``
+- ``rte_ethtool_net_get_stats64()``
+- ``rte_ethtool_net_vlan_rx_add_vid()``
+- ``rte_ethtool_net_vlan_rx_kill_vid()``
+- ``rte_ethtool_net_set_rx_mode()``
+- ``rte_ethtool_get_ringparam()``
+- ``rte_ethtool_set_ringparam()``

There are really common errors I'm fixing before applying:
(seen in most of other recent patches)

- When adding an item, a separation new line is needed
(the double blank lines are on purpose).
- A new example or driver is not an issue (should not ;),
so it should be in the "features" section.
- If the doc is not too large, a separate commit is not needed.

I know these comments are not read but I keep the hope that the
next series from other authors will meet the expectations.

Applied, thanks

Some feedbacks are welcome about the ethtool library.
If it has an interest and is well designed, it must be moved as
a real library.
The example directory is used as a staging here.
