Subject[BK PATCHES] 2.6.x net driver updates
I've tried to keep it to fixes, and created a separate queue
(net-drivers-2.[45]-exp) for non-fixes.

Linus, please do a

bk pull bk://kernel.bkbits.net/jgarzik/net-drivers-2.5

This will update the following files:

[PATCH] b44 enable interrupts after tx timeout (2.6-test version)

Resending the patch I sent some time ago for b44.c that nukes the
2.4 compatibility cruft as well.

I'll do one for 2.4.23pre6 ASAP, hopefully being able sync the driver fully
with the one in 2.6 (free_netdev() etc.).

[PATCH] - atmel wireless driver

1) Remove "#include <linux/version.h>" which was not needed and added
bad extra compile dependencies.

2) Fix typo in module description.

3) Make card detection code cope with buggy SMC CIS entries.

[PATCH] hang on ZEROCOPY/TSO when hitting no-Tx-resources

* Critical bug fix: under heavy Tx stress using ZEROCOPY or TSO, if we
ran out of Tx descriptors, we didn't calculate for the context
descritor used as the first of the ZEROCOPY/TSO send, nor do we clean
up the context desriptor bits in the case where the send isn't going
to fit, where we need to undo the mappings. This bug was introduced
with the 5.2.16 patch set which included a workaround for a hang
on 82544 over PCI-X. This workaround cause the check for no-Tx-
rosource logic to change, and this bug slipped in.

<ak@muc.de> (03/10/14 1.1363)
[PATCH] Fix warnings in defxx.c

Fix harmless 64bit warnings in defxx.c

<ak@muc.de> (03/10/14 1.1362)
[PATCH] Fix warnings in hp100

Fix some harmless integer/pointer size mismatch warnings in hp100.c
on 64bit compiles

<ak@muc.de> (03/10/14 1.1361)
[PATCH] Mark non 64bit clean network drivers

This marks some net drivers which are clearly not 64bit (judging from
the warnings) as !64BIT.

[hamradio bpqether] fix ancient debug line

removes a verry old debug line from the bpqethernet driver that
only fills logs.

<pe1rxq@amsat.org> (03/10/14 1.1359)
[hamradio scc] fix probe function

fix for the probe function of the scc driver which now uses
an uninitialised scc struct for requesting an io region.

<scott.feldman@intel.com> (03/10/14 1.1358)
[PATCH] ethtool_ops eeprom stuff

Finally got around to adding ethtool_ops to e100-3.0.x. I found a bug
with get_eeprom() and it seems to work best if we add get_eeprom_len() to
the ops list. Also moved check for offest + len < size into ethtool.c.

I was able to test [GS]EEPROM, PHYS_ID, GSTATS, GSTRINGS, and TEST, and
everything looks good.

Should I send same for 2.4?

<rmk+lkml@arm.linux.org.uk> (03/10/14 1.1357)
[PATCH] Fix pcnet_cs network hotplug

pcnet_cs registers the network device too early. The effect of this
is that the networking hotplug scripts are unable to bring the device
up automatically.

There are two issues:
- we were registering the net device before we finished setting up
the device (eg, reading the MAC address.)
- we were using DEV_CONFIG_PENDING to block the net device "open"
callback, and as we know the other methods may be called prior
to open.

My only concern with this patch is that we set info->node.dev_name
after we register the net device, so use of cardctl during the
hotplug scripts may give unexpected results. However, I am not
aware of anyone using cardctl to read the device name in network
hotplug scripts.

Please review and merge. Thanks.

[netdrvr xircom_cb] fix race in statistics pointer setting
