Did you mean to have these? Commit bd36b0ac appears to have
brought the mode bits change in.
Not trying to nitpick --- I am trying to find out if this was
caused by a git bug.

No idea, presumably not.
FWIW I never chmod anything source in the kernel tree, so I'm guessing
that maybe the patch associated with the commit contained mode bits?

Jeff, it seems you missed this patch:
From: Mikael Pettersson <mikpe@it.uu.se>
The arm ixp4xx_eth driver doesn't compile in 2.6.27-rc1:
CC [M] drivers/net/arm/ixp4xx_eth.o
drivers/net/arm/ixp4xx_eth.c: In function 'eth_poll':
drivers/net/arm/ixp4xx_eth.c:554: warning: passing argument 1 of 'dma_mapping_error' makes pointer from integer without a cast

make[2]: *** [drivers/net/arm] Error 2
make[1]: *** [drivers/net] Error 2
make: *** [drivers] Error 2
dma_mapping_error() changed in 2.6.27-rc1 to also take a device parameter,
but nobody bothered updating ixp4xx_eth.c. Fixed by passing the appropriate
device value in the dma_mapping_error() calls.
Tested on an ixp425 box.

I've pulled, but the WAN bits were borderline. If you couldn't pull
that WAN stuff in on time, that's just the way it goes sometimes.

Rough summary:
* fixes
* additions of the variety where only a few lines are added, to support
new hardware (forcedeth, netxen)
* a WAN update that got missed, and IMO should go in for 2.6.27. This
is addressing the complaint about too much stuff still using syncppp,
so things get switched more to generic HDLC. MUCH more typesafe, and
links directly with struct net_device, rather than through opaque void
pointers and syncppp-specific structs.
* bonding update with core bits previously ack'd by you
* that ethtool.h change increasing speed to 32 bits

- NAPI is a new driver API designed to reduce CPU and interrupt load

You requested it once, and I sent it immediately. I will re-send
it in a moment; please acknowledge receipt.

I have repeatedly requested the full patch, without receiving it. I
have requested the full patch via email, and not a URL to fetch and
reconstruct the patch description and sign-offs.
I searched my spam folder just now, just in case, but no sfc there
either.
We all agree the driver is OK for merging, I continue to wait for the
roll-up patch.
Jeff

Jeff, what happened here?
If Ben sent the full driver patch as Jeff asked for it, Jeff
should have added it by now. :-/

PHY Abstraction Layer
-(Updated 2006-11-30)
+(Updated 2008-04-08)
Purpose
@@ -291,3 +291,39 @@ Writing a PHY driver
Feel free to look at the Marvell, Cicada, and Davicom drivers in
drivers/net/phy/ for examples (the lxt and qsemi drivers have
not been tested as of this writing)
+
+Board Fixups
+
+ Sometimes the specific interaction between the platform and the PHY requires
+ special handling. For instance, to change where the PHY's clock input is,
+ or to add a delay to account for latency issues in the data path. In order
+ to support such contingencies, the PHY Layer allows platform code to register
+ fixups to be run when the PHY is brought up (or subsequently reset).
+
+ When the PHY Layer brings up a PHY it checks to see if there are any fixups
+ registered for it, matching based on UID (contained in the PHY device's phy_id
+ field) and the bus identifier (contained in phydev->dev.bus_id). Both must
+ match, however two constants, PHY_ANY_ID and PHY_ANY_UID, are provided as
+ wildcards for the bus ID and UID, respectively.
+
+ When a match is found, the PHY layer will invoke the run function associated
+ with the fixup. This function is passed a pointer to the phy_device of
+ interest. It should therefore only operate on that PHY.
+
+ The platform code can either register the fixup using phy_register_fixup():
+
+ int phy_register_fixup(const char *phy_id,
+ u32 phy_uid, u32 phy_uid_mask,
+ int (*run)(struct phy_device *));
+
+ Or using one of the two stubs, phy_register_fixup_for_uid() and
+ phy_register_fixup_for_id():
+
+ int phy_register_fixup_for_uid(u32 phy_uid, u32 phy_uid_mask,
+ int (*run)(struct phy_device *));
+ int phy_register_fixup_for_id(const char *phy_id,
+ int (*run)(struct phy_device *));
+
+ The stubs set one of the two matching criteria, and set the other one to
+ match anything.

I know, as I said: "for hardware device drivers" it's a lost
cause. Loopback is a software device.

The first part is right indeed, but the second part is breaking the
current usage of txq_stopped and
the logic that stops and restarts the Tx queue.
I can submit a patch fixing it. Plese let me know what's more convenient
for you.

Yes, we're all aware of this. Google for "david miller loopback lltx"
for a few examples...
Also, please do not strip CC's, that's quite annoying.

So, it sounds like Krishna's patch is ok, because the race does not

It sounds like I messed up.
cxgb3 does not use LLTX - The Chelsio driver does, thus should be
converted.

That's extremely unfortunate, hopefully you can update it to
use a model like tg3 and others use. LLTX is a lost cause
for hardware device drivers, and in fact we'd like to remove
it tree wide eventually.

Hi Divy,
But the race doesn't exist even for LLTX drivers these days. There is no
way two cpu's can execute the xmit handler at the same time.

The driver is cxgb3 here, it uses LLTX.

And the race is talking about LLTX, which S2IO doesn't use as
far as I can tell.

I feel this race cannot happen anymore. I think the fix for that race was
to introduce the
__LINK_STATE_QDISC_RUNNING bit thus eliminating any races between CPU's. If
one
CPU has called xmit, the other CPU will enqueue skbs (by holding the
queue_lock) and
exit from qdisc_run since it finds the bit set already.

Hi Jeff,
The first part of the patch removes the !netif_queue_stopped(dev).
It opens the race discussed a while ago between Stephen hemminger and
David Miller:
http://marc.info/?l=linux-netdev&m=113383224512427&w=2
The second part of the patch breaks the current usage of txq_stopped and
the logic that stops and restarts the Tx queue.
Cheers,
Divy

These two where meant to be from Laurent Pinchart, they do have
the correct signed-off lines in for him and start with "Patch from:". Is
there any chance of fixing the authour attribution now?

Hi Jeff,
I thought I had NAK'ed the patch modifying sge.c from Krishna Kumar.
Looking back at my answer at the time, I was obviously unclear.
Can you please revert the drivers/net/cxgb3sge.c change ?
Cheers,
Divy

- Linux network driver modules
-
- Do not mistake this for "README.modules" at the top-level
- directory! That document tells about modules in general, while
- this one tells only about network device driver modules.
-
- This is a potpourri of INSMOD-time(*) configuration options
- (if such exists) and their default values of various modules
- in the Linux network drivers collection.
-
- Some modules have also hidden (= non-documented) tunable values.
- The choice of not documenting them is based on general belief, that
- the less the user needs to know, the better. (There are things that
- driver developers can use, others should not confuse themselves.)
-
- In many cases it is highly preferred that insmod:ing is done
- ONLY with defining an explicit address for the card, AND BY
- NOT USING AUTO-PROBING!
-
- Now most cards have some explicitly defined base address that they
- are compiled with (to avoid auto-probing, among other things).
- If that compiled value does not match your actual configuration,
- do use the "io=0xXXX" -parameter for the insmod, and give there
- a value matching your environment.
-
- If you are adventurous, you can ask the driver to autoprobe
- by using the "io=0" parameter, however it is a potentially dangerous
- thing to do in a live system. (If you don't know where the
- card is located, you can try autoprobing, and after possible
- crash recovery, insmod with proper IO-address..)
-
- --------------------------
- (*) "INSMOD-time" means when you load module with
- /sbin/insmod you can feed it optional parameters.
- See "man insmod".
- --------------------------
-
-
- 8390 based Network Modules (Paul Gortmaker, Nov 12, 1995)
- --------------------------
-
-(Includes: smc-ultra, ne, wd, 3c503, hp, hp-plus, e2100 and ac3200)
-
-The 8390 series of network drivers now support multiple card systems without
-reloading the same module multiple times (memory efficient!) This is done by
-specifying multiple comma separated values, such as:
-
- insmod 3c503.o io=0x280,0x300,0x330,0x350 xcvr=0,1,0,1
-
-The above would have the one module controlling four 3c503 cards, with card 2
-and 4 using external transceivers. The "insmod" manual describes the usage
-of comma separated value lists.
-
-It is *STRONGLY RECOMMENDED* that you supply "io=" instead of autoprobing.
-If an "io=" argument is not supplied, then the ISA drivers will complain
-about autoprobing being not recommended, and begrudgingly autoprobe for
-a *SINGLE CARD ONLY* -- if you want to use multiple cards you *have* to
-supply an "io=0xNNN,0xQQQ,..." argument.
-
-The ne module is an exception to the above. A NE2000 is essentially an
-8390 chip, some bus glue and some RAM. Because of this, the ne probe is
-more invasive than the rest, and so at boot we make sure the ne probe is
-done last of all the 8390 cards (so that it won't trip over other 8390 based
-cards) With modules we can't ensure that all other non-ne 8390 cards have
-already been found. Because of this, the ne module REQUIRES an "io=0xNNN"
-argument passed in via insmod. It will refuse to autoprobe.
-
-It is also worth noting that auto-IRQ probably isn't as reliable during
-the flurry of interrupt activity on a running machine. Cards such as the
-ne2000 that can't get the IRQ setting from an EEPROM or configuration
-register are probably best supplied with an "irq=M" argument as well.

+fail_over_mac
+
+ Specifies whether active-backup mode should set all slaves to
+ the same MAC address (the traditional behavior), or, when
+ enabled, change the bond's MAC address when changing the
+ active interface (i.e., fail over the MAC address itself).
+
+ Fail over MAC is useful for devices that cannot ever alter
+ their MAC address, or for devices that refuse incoming
+ broadcasts with their own source MAC (which interferes with
+ the ARP monitor).
+
+ The down side of fail over MAC is that every device on the
+ network must be updated via gratuitous ARP, vs. just updating
+ a switch or set of switches (which often takes place for any
+ traffic, not just ARP traffic, if the switch snoops incoming
+ traffic to update its tables) for the traditional method. If
+ the gratuitous ARP is lost, communication may be disrupted.
+
+ When fail over MAC is used in conjuction with the mii monitor,
+ devices which assert link up prior to being able to actually
+ transmit and receive are particularly susecptible to loss of
+ the gratuitous ARP, and an appropriate updelay setting may be
+ required.
+
+ A value of 0 disables fail over MAC, and is the default. A
+ value of 1 enables fail over MAC. This option is enabled
+ automatically if the first slave added cannot change its MAC
+ address. This option may be modified via sysfs only when no
+ slaves are present in the bond.
+
+ This option was added in bonding version 3.2.0.

- The Digi International RightSwitch SE-X (dgrs) Device Driver
-
-This is a Linux driver for the Digi International RightSwitch SE-X
-EISA and PCI boards. These are 4 (EISA) or 6 (PCI) port Ethernet
-switches and a NIC combined into a single board. This driver can
-be compiled into the kernel statically or as a loadable module.
-
-There is also a companion management tool, called "xrightswitch".
-The management tool lets you watch the performance graphically,
-as well as set the SNMP agent IP and IPX addresses, IEEE Spanning
-Tree, and Aging time. These can also be set from the command line
-when the driver is loaded. The driver command line options are:
-
- debug=NNN Debug printing level
- dma=0/1 Disable/Enable DMA on PCI card
- spantree=0/1 Disable/Enable IEEE spanning tree
- hashexpire=NNN Change address aging time (default 300 seconds)
- ipaddr=A,B,C,D Set SNMP agent IP address i.e. 199,86,8,221
- iptrap=A,B,C,D Set SNMP agent IP trap address i.e. 199,86,8,221
- ipxnet=NNN Set SNMP agent IPX network number
- nicmode=0/1 Disable/Enable multiple NIC mode
-
-There is also a tool for setting up input and output packet filters
-on each port, called "dgrsfilt".
-
-Both the management tool and the filtering tool are available
-separately from the following FTP site:
-
- ftp://ftp.dgii.com/drivers/rightswitch/linux/
-
-When nicmode=1, the board and driver operate as 4 or 6 individual
-NIC ports (eth0...eth5) instead of as a switch. All switching
-functions are disabled. In the future, the board firmware may include
-a routing cache when in this mode.

-of the GNU General Public License, incorporated herein by reference.

-For information on purchasing a RightSwitch SE-4 or SE-6
-board, please contact Digi's sales department at 1-612-912-3444
-or 1-800-DIGIBRD. Outside the U.S., please check our Web page at:

-for sales offices worldwide. Tech support is also available through
-the channels listed on the Web site, although as long as I am
-employed on networking products at Digi I will be happy to provide
-any bug fixes that may be needed.

Mostly fixes or a few minor cleanups. I did permit ethtool support
addition to ucc_geth, since it's nice to be able to control your own
NICs using standard software.
Please pull from 'upstream-linus' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git upstream-linus
to receive the following updates:

Nothing highly notable. Wireless pull, and new blackfin eth driver
(didn't get merged with rest of blackfin, since additional review was
requested).
Please pull from 'upstream-linus' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git upstream-linus
to receive the following updates:

It's worse than just bonding related. This also causes a reliable hard
lockup with skge:
fresno:~# modprobe skge
fresno:~# ip li set eth2 up
fresno:~# ip li set eth2 down
fresno:~# ip li set eth3 up
The server locks up there. Nothing is printed to console and it takes a
power cycle to fix the problem.
eth2 and eth3 are both ports on an SK-9844 dual-port card. The test above
is with 2.6.22. I've also had it fail with .21.*, .20.*, and several
other kernels.

This is probably going to cause a new entry in regressions list, as at
least Chris Stromsoe has reported bonding-related problems with skge that
don't happen with sklin -

-
-
-1 Overview
-===========
-
-The sk98lin driver supports the Marvell Yukon and SysKonnect
-SK-98xx/SK-95xx compliant Gigabit Ethernet Adapter on Linux. It has
-been tested with Linux on Intel/x86 machines.
-***
-
-
-2 Required Files
-=================
-
-The linux kernel source.
-No additional files required.
-***
-
-
-3 Installation
-===============
-
-It is recommended to download the latest version of the driver from the
-SysKonnect web site www.syskonnect.com. If you have downloaded the latest
-driver, the Linux kernel has to be patched before the driver can be
-installed. For details on how to patch a Linux kernel, refer to the
-patch.txt file.
-
-3.1 Driver Installation
-------------------------
-
-The following steps describe the actions that are required to install
-the driver and to start it manually. These steps should be carried
-out for the initial driver setup. Once confirmed to be ok, they can
-be included in the system start.
-
-NOTE 1: To perform the following tasks you need 'root' access.
-
-NOTE 2: In case of problems, please read the section "Troubleshooting"
- below.
-
-The driver can either be integrated into the kernel or it can be compiled
-as a module. Select the appropriate option during the kernel
-configuration.
-
-Compile/use the driver as a module
-----------------------------------
-To compile the driver, go to the directory /usr/src/linux and
-execute the command "make menuconfig" or "make xconfig" and proceed as
-follows:
-
-To integrate the driver permanently into the kernel, proceed as follows:
-
-1. Select the menu "Network device support" and then "Ethernet(1000Mbit)"
-2. Mark "Marvell Yukon Chipset / SysKonnect SK-98xx family support"
- with (*)
-3. Build a new kernel when the configuration of the above options is
- finished.
-4. Install the new kernel.
-5. Reboot your system.
-
-To use the driver as a module, proceed as follows:
-
-1. Enable 'loadable module support' in the kernel.
-2. For automatic driver start, enable the 'Kernel module loader'.
-3. Select the menu "Network device support" and then "Ethernet(1000Mbit)"
-4. Mark "Marvell Yukon Chipset / SysKonnect SK-98xx family support"
- with (M)
-5. Execute the command "make modules".
-6. Execute the command "make modules_install".
- The appropriate modules will be installed.
-7. Reboot your system.
-
-
-Load the module manually
-------------------------
-To load the module manually, proceed as follows:
-
-1. Enter "modprobe sk98lin".
-2. If a Marvell Yukon or SysKonnect SK-98xx adapter is installed in
- your computer and you have a /proc file system, execute the command:
- "ls /proc/net/sk98lin/"
- This should produce an output containing a line with the following
- format:
- eth0 eth1 ...
- which indicates that your adapter has been found and initialized.
-
- NOTE 1: If you have more than one Marvell Yukon or SysKonnect SK-98xx
- adapter installed, the adapters will be listed as 'eth0',
- 'eth1', 'eth2', etc.
- For each adapter, repeat steps 3 and 4 below.
-
- NOTE 2: If you have other Ethernet adapters installed, your Marvell
- Yukon or SysKonnect SK-98xx adapter will be mapped to the
- next available number, e.g. 'eth1'. The mapping is executed
- automatically.
- The module installation message (displayed either in a system
- log file or on the console) prints a line for each adapter
- found containing the corresponding 'ethX'.
-
-3. Select an IP address and assign it to the respective adapter by
- entering:
- ifconfig eth0 <ip-address>
- With this command, the adapter is connected to the Ethernet.
-
- SK-98xx Gigabit Ethernet Server Adapters: The yellow LED on the adapter
- is now active, the link status LED of the primary port is active and
- the link status LED of the secondary port (on dual port adapters) is
- blinking (if the ports are connected to a switch or hub).
- SK-98xx V2.0 Gigabit Ethernet Adapters: The link status LED is active.
- In addition, you will receive a status message on the console stating
- "ethX: network connection up using port Y" and showing the selected
- connection parameters (x stands for the ethernet device number
- (0,1,2, etc), y stands for the port name (A or B)).
-
- NOTE: If you are in doubt about IP addresses, ask your network
- administrator for assistance.
-
-4. Your adapter should now be fully operational.
- Use 'ping <otherstation>' to verify the connection to other computers
- on your network.
-5. To check the adapter configuration view /proc/net/sk98lin/[devicename].
- For example by executing:
- "cat /proc/net/sk98lin/eth0"
-
-Unload the module
------------------
-To stop and unload the driver modules, proceed as follows:
-
-1. Execute the command "ifconfig eth0 down".
-2. Execute the command "rmmod sk98lin".
-
-3.2 Inclusion of adapter at system start
------------------------------------------
-
-Since a large number of different Linux distributions are
-available, we are unable to describe a general installation procedure
-for the driver module.
-Because the driver is now integrated in the kernel, installation should
-be easy, using the standard mechanism of your distribution.
-Refer to the distribution's manual for installation of ethernet adapters.
-
-***
-
-4 Driver Parameters
-====================
-
-Parameters can be set at the command line after the module has been
-loaded with the command 'modprobe'.
-In some distributions, the configuration tools are able to pass parameters
-to the driver module.
-
-If you use the kernel module loader, you can set driver parameters
-in the file /etc/modprobe.conf (or /etc/modules.conf in 2.4 or earlier).
-To set the driver parameters in this file, proceed as follows:
-
-1. Insert a line of the form :
- options sk98lin ...
- For "...", the same syntax is required as described for the command
- line parameters of modprobe below.
-2. To activate the new parameters, either reboot your computer
- or
- unload and reload the driver.
- The syntax of the driver parameters is:
-
- modprobe sk98lin parameter=value1[,value2[,value3...]]
-
- where value1 refers to the first adapter, value2 to the second etc.
-
-NOTE: All parameters are case sensitive. Write them exactly as shown
- below.
-
-Example:
-Suppose you have two adapters. You want to set auto-negotiation
-on the first adapter to ON and on the second adapter to OFF.
-You also want to set DuplexCapabilities on the first adapter
-to FULL, and on the second adapter to HALF.
-Then, you must enter:
-
- modprobe sk98lin AutoNeg_A=On,Off DupCap_A=Full,Half
-
-NOTE: The number of adapters that can be configured this way is
- limited in the driver (file skge.c, constant SK_MAX_CARD_PARAM).
- The current limit is 16. If you happen to install
- more adapters, adjust this and recompile.
-
-
-4.1 Per-Port Parameters
-------------------------
-
-These settings are available for each port on the adapter.
-In the following description, '?' stands for the port for
-which you set the parameter (A or B).
-
-Speed
------
-Parameter: Speed_?
-Values: 10, 100, 1000, Auto
-Default: Auto
-
-This parameter is used to set the speed capabilities. It is only valid
-for the SK-98xx V2.0 copper adapters.
-Usually, the speed is negotiated between the two ports during link
-establishment. If this fails, a port can be forced to a specific setting
-with this parameter.
-
-Auto-Negotiation
-----------------
-Parameter: AutoNeg_?
-Values: On, Off, Sense
-Default: On
-
-The "Sense"-mode automatically detects whether the link partner supports
-auto-negotiation or not.
-
-Duplex Capabilities
--------------------
-Parameter: DupCap_?
-Values: Half, Full, Both
-Default: Both
-
-This parameters is only relevant if auto-negotiation for this port is
-not set to "Sense". If auto-negotiation is set to "On", all three values
-are possible. If it is set to "Off", only "Full" and "Half" are allowed.
-This parameter is useful if your link partner does not support all
-possible combinations.
-
-Flow Control
-------------
-Parameter: FlowCtrl_?
-Values: Sym, SymOrRem, LocSend, None
-Default: SymOrRem
-
-This parameter can be used to set the flow control capabilities the
-port reports during auto-negotiation. It can be set for each port
-individually.
-Possible modes:
- -- Sym = Symmetric: both link partners are allowed to send
- PAUSE frames
- -- SymOrRem = SymmetricOrRemote: both or only remote partner
- are allowed to send PAUSE frames
- -- LocSend = LocalSend: only local link partner is allowed
- to send PAUSE frames
- -- None = no link partner is allowed to send PAUSE frames
-
-NOTE: This parameter is ignored if auto-negotiation is set to "Off".
-
-Role in Master-Slave-Negotiation (1000Base-T only)
---------------------------------------------------
-Parameter: Role_?
-Values: Auto, Master, Slave
-Default: Auto
-
-This parameter is only valid for the SK-9821 and SK-9822 adapters.
-For two 1000Base-T ports to communicate, one must take the role of the
-master (providing timing information), while the other must be the
-slave. Usually, this is negotiated between the two ports during link
-establishment. If this fails, a port can be forced to a specific setting
-with this parameter.
-
-
-4.2 Adapter Parameters
------------------------
-
-Connection Type (SK-98xx V2.0 copper adapters only)
----------------
-Parameter: ConType
-Values: Auto, 100FD, 100HD, 10FD, 10HD
-Default: Auto
-
-The parameter 'ConType' is a combination of all five per-port parameters
-within one single parameter. This simplifies the configuration of both ports
-of an adapter card! The different values of this variable reflect the most
-meaningful combinations of port parameters.
-
-The following table shows the values of 'ConType' and the corresponding
-combinations of the per-port parameters:
-
- ConType | DupCap AutoNeg FlowCtrl Role Speed
- ----------+------------------------------------------------------
- Auto | Both On SymOrRem Auto Auto
- 100FD | Full Off None Auto (ignored) 100
- 100HD | Half Off None Auto (ignored) 100
- 10FD | Full Off None Auto (ignored) 10
- 10HD | Half Off None Auto (ignored) 10
-
-Stating any other port parameter together with this 'ConType' variable
-will result in a merged configuration of those settings. This due to
-the fact, that the per-port parameters (e.g. Speed_? ) have a higher
-priority than the combined variable 'ConType'.
-
-NOTE: This parameter is always used on both ports of the adapter card.
-
-Interrupt Moderation
---------------------
-Parameter: Moderation
-Values: None, Static, Dynamic
-Default: None
-
-Interrupt moderation is employed to limit the maximum number of interrupts
-the driver has to serve. That is, one or more interrupts (which indicate any
-transmit or receive packet to be processed) are queued until the driver
-processes them. When queued interrupts are to be served, is determined by the
-'IntsPerSec' parameter, which is explained later below.
-
-Possible modes:
-
- -- None - No interrupt moderation is applied on the adapter card.
- Therefore, each transmit or receive interrupt is served immediately
- as soon as it appears on the interrupt line of the adapter card.
-
- -- Static - Interrupt moderation is applied on the adapter card.
- All transmit and receive interrupts are queued until a complete
- moderation interval ends. If such a moderation interval ends, all
- queued interrupts are processed in one big bunch without any delay.
- The term 'static' reflects the fact, that interrupt moderation is
- always enabled, regardless how much network load is currently
- passing via a particular interface. In addition, the duration of
- the moderation interval has a fixed length that never changes while
- the driver is operational.
-
- -- Dynamic - Interrupt moderation might be applied on the adapter card,
- depending on the load of the system. If the driver detects that the
- system load is too high, the driver tries to shield the system against
- too much network load by enabling interrupt moderation. If - at a later
- time - the CPU utilization decreases again (or if the network load is
- negligible) the interrupt moderation will automatically be disabled.
-
-Interrupt moderation should be used when the driver has to handle one or more
-interfaces with a high network load, which - as a consequence - leads also to a
-high CPU utilization. When moderation is applied in such high network load
-situations, CPU load might be reduced by 20-30%.
-
-NOTE: The drawback of using interrupt moderation is an increase of the round-
-trip-time (RTT), due to the queueing and serving of interrupts at dedicated
-moderation times.
-
-Interrupts per second
----------------------
-Parameter: IntsPerSec
-Values: 30...40000 (interrupts per second)
-Default: 2000
-
-This parameter is only used if either static or dynamic interrupt moderation
-is used on a network adapter card. Using this parameter if no moderation is
-applied will lead to no action performed.
-
-This parameter determines the length of any interrupt moderation interval.
-Assuming that static interrupt moderation is to be used, an 'IntsPerSec'
-parameter value of 2000 will lead to an interrupt moderation interval of
-500 microseconds.
-
-NOTE: The duration of the moderation interval is to be chosen with care.
-At first glance, selecting a very long duration (e.g. only 100 interrupts per
-second) seems to be meaningful, but the increase of packet-processing delay
-is tremendous. On the other hand, selecting a very short moderation time might
-compensate the use of any moderation being applied.
-
-
-Preferred Port
---------------
-Parameter: PrefPort
-Values: A, B
-Default: A
-
-This is used to force the preferred port to A or B (on dual-port network
-adapters). The preferred port is the one that is used if both are detected
-as fully functional.
-
-RLMT Mode (Redundant Link Management Technology)
-------------------------------------------------
-Parameter: RlmtMode
-Values: CheckLinkState,CheckLocalPort, CheckSeg, DualNet
-Default: CheckLinkState
-
-RLMT monitors the status of the port. If the link of the active port
-fails, RLMT switches immediately to the standby link. The virtual link is
-maintained as long as at least one 'physical' link is up.
-
-Possible modes:
-
- -- CheckLinkState - Check link state only: RLMT uses the link state
- reported by the adapter hardware for each individual port to
- determine whether a port can be used for all network traffic or
- not.
-
- -- CheckLocalPort - In this mode, RLMT monitors the network path
- between the two ports of an adapter by regularly exchanging packets
- between them. This mode requires a network configuration in which
- the two ports are able to "see" each other (i.e. there must not be
- any router between the ports).
-
- -- CheckSeg - Check local port and segmentation: This mode supports the
- same functions as the CheckLocalPort mode and additionally checks
- network segmentation between the ports. Therefore, this mode is only
- to be used if Gigabit Ethernet switches are installed on the network
- that have been configured to use the Spanning Tree protocol.
-
- -- DualNet - In this mode, ports A and B are used as separate devices.
- If you have a dual port adapter, port A will be configured as eth0
- and port B as eth1. Both ports can be used independently with
- distinct IP addresses. The preferred port setting is not used.
- RLMT is turned off.
-
-NOTE: RLMT modes CLP and CLPSS are designed to operate in configurations
- where a network path between the ports on one adapter exists.
- Moreover, they are not designed to work where adapters are connected
- back-to-back.
-***
-
-
-5 Large Frame Support
-======================
-
-The driver supports large frames (also called jumbo frames). Using large
-frames can result in an improved throughput if transferring large amounts
-of data.
-To enable large frames, set the MTU (maximum transfer unit) of the
-interface to the desired value (up to 9000), execute the following
-command:
- ifconfig eth0 mtu 9000
-This will only work if you have two adapters connected back-to-back
-or if you use a switch that supports large frames. When using a switch,
-it should be configured to allow large frames and auto-negotiation should
-be set to OFF. The setting must be configured on all adapters that can be
-reached by the large frames. If one adapter is not set to receive large
-frames, it will simply drop them.
-
-You can switch back to the standard ethernet frame size by executing the
-following command:
- ifconfig eth0 mtu 1500
-
-To permanently configure this setting, add a script with the 'ifconfig'
-line to the system startup sequence (named something like "S99sk98lin"
-in /etc/rc.d/rc2.d).
-***
-
-
-6 VLAN and Link Aggregation Support (IEEE 802.1, 802.1q, 802.3ad)
-==================================================================
-
-The Marvell Yukon/SysKonnect Linux drivers are able to support VLAN and
-Link Aggregation according to IEEE standards 802.1, 802.1q, and 802.3ad.
-These features are only available after installation of open source
-modules available on the Internet:
-For VLAN go to: http://www.candelatech.com/~greear/vlan.html
-For Link Aggregation go to: http://www.st.rim.or.jp/~yumo
-
-NOTE: SysKonnect GmbH does not offer any support for these open source
- modules and does not take the responsibility for any kind of
- failures or problems arising in connection with these modules.
-
-NOTE: Configuring Link Aggregation on a SysKonnect dual link adapter may
- cause problems when unloading the driver.
-
-
-7 Troubleshooting
-==================
-
-If any problems occur during the installation process, check the
-following list:
-
-
-Problem: The SK-98xx adapter cannot be found by the driver.
-Solution: In /proc/pci search for the following entry:
- 'Ethernet controller: SysKonnect SK-98xx ...'
- If this entry exists, the SK-98xx or SK-98xx V2.0 adapter has
- been found by the system and should be operational.
- If this entry does not exist or if the file '/proc/pci' is not
- found, there may be a hardware problem or the PCI support may
- not be enabled in your kernel.
- The adapter can be checked using the diagnostics program which
- is available on the SysKonnect web site:
- www.syskonnect.com
-
- Some COMPAQ machines have problems dealing with PCI under Linux.
- This problem is described in the 'PCI howto' document
- (included in some distributions or available from the
- web, e.g. at 'www.linux.org').
-
-
-Problem: Programs such as 'ifconfig' or 'route' cannot be found or the
- error message 'Operation not permitted' is displayed.
-Reason: You are not logged in as user 'root'.
-Solution: Logout and login as 'root' or change to 'root' via 'su'.
-
-
-Problem: Upon use of the command 'ping <address>' the message
- "ping: sendto: Network is unreachable" is displayed.
-Reason: Your route is not set correctly.
-Solution: If you are using RedHat, you probably forgot to set up the
- route in the 'network configuration'.
- Check the existing routes with the 'route' command and check
- if an entry for 'eth0' exists, and if so, if it is set correctly.
-
-
-Problem: The driver can be started, the adapter is connected to the
- network, but you cannot receive or transmit any packets;
- e.g. 'ping' does not work.
-Reason: There is an incorrect route in your routing table.
-Solution: Check the routing table with the command 'route' and read the
- manual help pages dealing with routes (enter 'man route').
-
-NOTE: Although the 2.2.x kernel versions generate the routing entry
- automatically, problems of this kind may occur here as well. We've
- come across a situation in which the driver started correctly at
- system start, but after the driver has been removed and reloaded,
- the route of the adapter's network pointed to the 'dummy0'device
- and had to be corrected manually.
-
-
-Problem: Your computer should act as a router between multiple
- IP subnetworks (using multiple adapters), but computers in
- other subnetworks cannot be reached.
-Reason: Either the router's kernel is not configured for IP forwarding
- or the routing table and gateway configuration of at least one
- computer is not working.
-
-Problem: Upon driver start, the following error message is displayed:
- "eth0: -- ERROR --
- Class: internal Software error
- Nr: 0xcc
- Msg: SkGeInitPort() cannot init running ports"
-Reason: You are using a driver compiled for single processor machines
- on a multiprocessor machine with SMP (Symmetric MultiProcessor)
- kernel.
-Solution: Configure your kernel appropriately and recompile the kernel or
- the modules.
-
-
-
-If your problem is not listed here, please contact SysKonnect's technical
-support for help (linux@syskonnect.de).
-When contacting our technical support, please ensure that the following
-information is available:
-- System Manufacturer and HW Informations (CPU, Memory... )
-- PCI-Boards in your system
-- Distribution
-- Kernel version
-- Driver version

- <file:Documentation/networking/sk98lin.txt> for more information about
- optional driver parameters.
- Questions concerning this driver may be addressed to:
- <linux@syskonnect.de>
-
- If you want to compile this driver as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want),
- say M here and read <file:Documentation/kbuild/modules.txt>. The module will
- be called sk98lin. This is recommended.
+ If unsure, say N.

Try removing the one in front of the comma, it makes the count -1. And I
wrote, probably a good 20 years ago, a gizmo I called cntx that found that
stuff for you. I occasionally use it to run over a section of the kernel
tree, but it rarely finds anything to fuss about. And I really do need to
make it handle shell expansions so you don't have write a quick script to
have it scan everything in a directory. However I suspect that most of you
already have such a tool in your bag of tricks.

Me neither. Simple script does that for me ;) Not sure where exactly
the parenthesis is missing so I leave it up to someone (the author?)
who knows better.

(just sent this upstream to Linus and Andrew)
The only really notable thing is the merging of the wireless driver for

Dan posted it to linux-wireless@vger.kernel.org on 13 Feb 2007.
The description in the body is quoted below:
Correct assignment of DOT1XENABLE in WE-19 codepaths.
RX_UNENCRYPTED_EAPOL = 1 really means setting DOT1XENABLE _off_, and
vice versa. The original WE-19 patch erroneously reversed that. This
patch fixes association with unencrypted and WEP networks when using
wpa_supplicant.
It also adds two missing break statements that, left out, could result
in incorrect card configuration.
Please commit to both development and stable branches.

The patch description clearly indicates those break statements, and
they're also clearly necessary.

Where did this spring from ?
I see no posting of this patch let alone
an ACK.
The patch is also doing rather more than the description -
It is inserting extra breaks into a switch statement with
no comment as to why.

[just sent upstream to Andrew & Linus; patch available in git, it's too
large to post]
Nothing major of interest. A couple new drivers (ehea, qla3xxx,
ep93xx_eth), a lot of trailing whitespace killed, a deleted MIPS driver,
e1000 update, ...

Good news. The latest -git driver seems to fix the problem.
So maybe something got broken with the double request_irq.

You misunderstood me:
Due to a broken patch, the driver did
request_irq(irqnum, handler,...)
twice. Thus the irq handler was registered twice. The rx synchronization
assumes that the irq handler doesn't run concurrently. I'm not sure what
happens if the irq handler is registered twice: is it possible that it
runs twice at the same time, i.e. is the synchronization in the irq
subsystem irq number or registration call based?

I don't have any good ideas, please try to figure out what's wrong. Is
there a debug switch for the network layer that forces the network layer
to verify the CHECKSUM_UNNECESSARY blocks?

The system has two Forcedeth ports, but only one has a cable connected.
I don't think there is any parallelism. Just one connection with a lot
of data. It didn't happen with 2.6.16.
If you don't have any other good ideas I will try to track it down.

No idea, but unlikely. The fix removes a duplicate request_irq call. Is
it possible that the both instances run concurrently?

bcm43xx: reduce the size of bcm43xx_private by removing unneeded members.
bcm43xx: Fix crash on ifdown, by being careful in pio/dma freeing.
bcm43xx: Remove the workaround in dummy_transmission,
bcm43xx: Do boardflags workarounds for specific boards.
bcm43xx: properly mask txctl1 before writing it to hardware.
bcm43xx: remove check for mmio length, as it differs among platforms. (especially embedded)
bcm43xx: fix some gpio register trashing (hopefully :D)
bcm43xx: merge all iwmode code into the set_iwmode function.
bcm43xx: some IRQ handler cleanups.
bcm43xx: set default attenuation values.
bcm43xx: sync interference mitigation code to the specs.
