From: Jesse Brandeburg <jesse.brandeburg@intel.com>
This is the driver for the Intel(R) Ethernet Controller XL710 Family.
This driver is targeted at basic ethernet functionality only, and will be
improved upon further as time goes on.
This patch mail contains the driver entry points but does not include transmit
and receive (see the next patch in the series) routines.

v1: this is the first submittal
v2: changes resulting from first round of feedback, including
better 32 bit compatibility
remove messages on alloc failure
use macros instead of functions for debug print
use ether_addr
check mac addr validity, fail earlier
use temp variables in stats collection
some changes due to internal spec clarifications
const'ify some strings
convert some macros to functions for stats gathering
use strlcpy
no trans_start
minor cleanups
remove unnecessary napi_synchronize
remove unnecessary netdev ops assignment function
use rtnl_link_stats64
fix up pci_using_dac/NETIF_F_HIGHDMA

First, I see no reason to specify GFP_ATOMIC here, code paths that
call this thing even have comments above them like:
--------------------
+ * Do *NOT* hold the lock when calling this as the memory allocation routines
+ * called are not going to be atomic context safe
--------------------
Secondly, use dma_zalloc_coherent() if you want __GFP_ZERO.

Since there is absolutely no context passed into these helper routines,
the log messages are less useful than they could be. If you did this
right you could use netdev_info() or dev_info() here.

I think this brief and common name is asking for namespace collision

I think something using rounddown_pow_of_two() would accomplish this.
Perhaps:
if (!is_power_of_2(x))
x = rounddown_pow_of_two(x);

Perhaps we went a little too far in trying for loosely coupled code? We'll add enough context for dev_info().

I understand the aesthetics as it does make the code look a little cleaner, and we can do this with a lot of our functions. However, there are several instances where one declaration initialization depends on a previous declaration, and trying to organize by line length breaks these relationships. Do you mind if we're not perfect on following this one?
Also, perhaps I haven't watched closely enough, but I don't remember seeing this comment on other code. Is this a new recommendation that will be going into the CodingStyle document?
Thanks,

Put the assignments that can match the ordering rule into the
declarations, put the remaining ones on seperate lines after
the declarations.

If you want to use an enum I suggest you shorten the name to something
like i40e_sc, otherwise the function declaration lines will become
longer than needed and we'll have to split the arguments across multiple
lines more than necessary.

Shouldn't this be indented by another tab instead of the spaces? Maybe
you could use netdev_info() instead of pr_info() so it's easier to
understand which device is meant.

VSI is short for Virtual Station Interface - essentially a generic name for VMDq and VF type virtual interfaces into a network device. It's part of the nomenclature coming from the IEEE 802.1Qbg work. In our driver, a VSI is how we collect sets of Tx/Rx queues and mac address filters for HW offloading of network virtualization. Not every VSI will have a netdev associated to it, tho' it is a handy way to think about how they are used.

This is where I whine about it being too late to change such a basic datatype in all the shared code of our other OS drivers that use it, and no one wants to hear it. You're right, of course, and we'll see what we can do about compressing it a little.

Some of these choices are driven by our use of code that is shared with other OSs.

It seemed like a reasonable choice for an often-referenced object and the primary focus of the function. I understand your concern, but I think when used consistently it's not quite the problem that some other willy-nilly single letter variables can be.

The reason is that it isn't needed/used anywhere else, it is simply a constant used in this function to set an arbitrary list length for processing the filters. However, since it is slightly related to the amount of data we can send down in the AQ request, perhaps we can compute a useful constant based on buffer size rather than using a random #define.

We have to be careful about our use of netdev_info() because not always is there a netdev related to the operation. For example, if we're adding filters on behalf of one of our VFs, the netdev is in the VF context and we don't have access to it.

VEBs usually have an uplink to the physical MAC port, and act as a physical bridge for offloading bridging and filtering duties. A floating VEB is essentially a bridge with no link to the outside, useful for offloading internal (private) bridging between VMs. With the lack of support in the kernel and userspace at this time for this offload concept, this comment may not be useful, and we can make it disappear for now.

No good reason other than it is indexing the vsi array; we can change that name.

If MSIX setup failed, then we'll be using the misc handler for either MSI or Legacy IRQ. This is not intended to be the normal case. Usually the misc handler will be dealing with our 0-th MSIX vector.

It was added to separate the subtask operations from the "I'm done" routine.

Should use either tab or space after cd_cmd, cd_mss but please don't mix
them.

We don't suggest that anymore, because it's completely unnecessary
with the way the macros are implemented.

Okay, good to know. I see it being used frequently in igb, ixgbe so my
assumption was it's the way to go.

This patch contains the ethtool interface and implementation.
The goal in this patch series is minimal functionality while not
including much in the way of "set support."

v1: this is the initial submittal
v2: changes due to first round of netdev feedback, including:
remove unimplemented ethtool skeleton functions
as per bwh, use better stats naming like tx-N
don't report stats we won't change
remove buggy static variable
don't force n_len
don't double buffer in get_drvinfo
use strlcpy
don't use hacks for old kernels
use some simplifying macros
use rtnl_link_stats64
report correct speeds

While not part of this patch series, an i40evf driver is on its
way, and uses these files to communicate to the PF driver.
This patch contains the header and implementation files for the
PF to VF interface.

+/* Description:
+ * This header file describes the VF-PF communication protocol used
+ * by the various i40e drivers.
+ *
+ * Admin queue buffer usage:
+ * desc->opcode is always i40e_aqc_opc_send_msg_to_pf
+ * flags, retval, datalen, and data addr are all used normally.
+ * Firmware copies the cookie fields when sending messages between the PF and
+ * VF, but uses all other fields internally. Due to this limitation, we
+ * must send all messages as "indirect", i.e. using an external buffer.
+ *
+ * All the vsi indexes are relative to the VF. Each VF can have maximum of
+ * three VSIs. All the queue indexes are relative to the VSI. Each VF can
+ * have a maximum of sixteen queues for all of its VSIs.
+ *
+ * The PF is required to return a status code in v_retval for all messages
+ * except RESET_VF, which does not require any response. The return value is of
+ * i40e_status_code type, defined in the i40e_type.h.
+ *
+ * In general, VF driver initialization should roughly follow the order of these
+ * opcodes. The VF driver must first validate the API version of the PF driver,
+ * then request a reset, then get resources, then configure queues and
+ * interrupts. After these operations are complete, the VF driver may start
+ * its queues, optionally add MAC and VLAN filters, and process traffic.

From: Jesse Brandeburg <jesse.brandeburg@intel.com>
As with other Intel drivers, we have a set of code that is shared
by multiple OS drivers. Whenever possible this code has been
machine modified to use native Linux kernel interfaces. A very
small adaptation layer is in i40e_osdep.h.
This patch implements the hardware specific init and management
that is OS agnostic.
Intel does wish to maintain exclusive Copyright to these files,
and will work with the community to implement requested changes
or transfer Copyright for larger patches. If you do see an issue
with this code please email us and we will address any concerns
in a timely manner.

To: davem; +Cc: e1000-devel, netdev, Jesse Brandeburg, gospo, sassmann
From: Jesse Brandeburg <jesse.brandeburg@intel.com>
This driver includes a debugfs interface for developers to get more hardware
information in real-time.
This patch also includes a sysfs interface for root users to use to help
configure/view some of the internal parameters of the device.

+Linux Base Driver for the Intel(R) Ethernet Controller XL710 Family
+===================================================================
+
+Intel i40e Linux driver.
+Copyright(c) 2013 Intel Corporation.
+
+Contents
+========
+

+
+Identifying Your Adapter
+========================
+
+The driver in this release is compatible with the Intel Ethernet
+Controller XL710 Family.
+
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:
+
+ http://support.intel.com/support/network/sb/CS-012904.htm
+
+
+Enabling the driver
+===================
+
+The driver is enabled via the standard kernel configuration system,
+using the make command:
+
+ Make oldconfig/silentoldconfig/menuconfig/etc.
+
+The driver is located in the menu structure at:
+
+ -> Device Drivers
+ -> Network device support (NETDEVICES [=y])
+ -> Ethernet driver support
+ -> Intel devices
+ -> Intel(R) Ethernet Controller XL710 Family
+
+Additional Configurations
+=========================
+
+ Generic Receive Offload (GRO)
+ -----------------------------
+ The driver supports the in-kernel software implementation of GRO. GRO has
+ shown that by coalescing Rx traffic into larger chunks of data, CPU
+ utilization can be significantly reduced when under large Rx load. GRO is
+ an evolution of the previously-used LRO interface. GRO is able to coalesce
+ other protocols besides TCP. It's also safe to use with configurations that
+ are problematic for LRO, namely bridging and iSCSI.
+
+ Ethtool
+ -------
+ The driver utilizes the ethtool interface for driver configuration and
+ diagnostics, as well as displaying statistical information. The latest
+ ethtool version is required for this functionality.
+
+ The latest release of ethtool can be found from
+ https://www.kernel.org/pub/software/network/ethtool
+
+ Data Center Bridging (DCB)
+ --------------------------
+ DCB configuration is not currently supported.
+
+ FCoE
+ ----
+ Fiber Channel over Ethernet (FCoE) hardware offload is not currently
+ supported.
+
+ MAC and VLAN anti-spoofing feature
+ ----------------------------------
+ When a malicious driver attempts to send a spoofed packet, it is dropped by
+ the hardware and not transmitted. An interrupt is sent to the PF driver
+ notifying it of the spoof attempt.
+
+ When a spoofed packet is detected the PF driver will send the following
+ message to the system log (displayed by the "dmesg" command):
+
+ Spoof event(s) detected on VF (n)
+
+ Where n=the VF that attempted to do the spoofing.
+
+
+Performance Tuning
+==================
+
+An excellent article on performance tuning can be found at:
+
+http://www.redhat.com/promo/summit/2008/downloads/pdf/Thursday/Mark_Wagner.pdf
+
+
+Known Issues
+============
+
+
+Support
+=======
+
+For general information, go to the Intel support website at:
+
+ http://support.intel.com
+
+or the Intel Wired Networking project hosted by Sourceforge at:
+
+ http://e1000.sourceforge.net
+
+If an issue is identified with the released source code on the supported
+kernel with a supported adapter, email the specific information related
+to the issue to e1000-devel@lists.sourceforge.net and copy
+netdev@vger.kernel.org.
