* [PATCH] Tulip: don't initialize SBE xT3E3 WAN ports.
From: Krzysztof Halasa @ 2010-07-31 9:32 UTC (permalink / raw)
To: David Miller; +Cc: netdev
SBE 2T3E3 cards use DECchips 21143 but they need a different driver.
Don't even try to use a normal tulip driver with them.

* [PATCH staging] Add SBE 2T3E3 WAN driver
From: Krzysztof Halasa @ 2010-07-31 9:53 UTC (permalink / raw)
To: Greg KH; +Cc: netdev
This is a driver for SBE Inc.'s dual port T3/E3 WAN cards. Based on
their original GPLed driver.
It needs at least a new generic HDLC setup code (not yet written) before
moving to drivers/net/wan.

I have generated the patch against v2.6.35-rc6. Compiles cleanly.
Please let me know if it needs extra changes for e.g. staging tree.
Thanks.

* [PATCH] net/rose: Use GFP_ATOMIC

To: Ralf Baechle, David S. Miller, linux-hams, linux-kernel, netdev,

From: Julia Lawall <julia@diku.dk>
The other calls to kmalloc in the same function use GFP_ATOMIC, and indeed
two locks are held within the body of the function.
The semantic match that finds this problem is as follows:

Shouldn't the callers (get_unique_tuple in nf_nat_core.c) ideally
return NF_DROP or something such that connections that cannot be
uniquely mangled be rejected rather than forwarded without mangling?

* [PATCH] Multiqueue macvtap driver
From: Krishna Kumar @ 2010-07-31 13:57 UTC (permalink / raw)
To: davem, arnd; +Cc: netdev, Krishna Kumar, mst
From: Krishna Kumar <krkumar2@in.ibm.com>
Implement multiqueue facility for macvtap driver. The idea is that
a macvtap device can be opened multiple times and the fd's can be
used to register eg, as backend for vhost.
Please review.

The 1 looks strange. It's more common to express this without
a condition, as in (i = 0; ; ++off).

* [PULL REQ] WAN: LMC driver
From: Krzysztof Halasa @ 2010-07-31 14:36 UTC (permalink / raw)
To: David Miller; +Cc: netdev
David,
I have done a bit of work on the LMC WAN driver. It's still far from
perfection, though I think it's a visible improvement. It merges with
your current "next" tree cleanly. I'll also post the individual patches.
Please pull. Thanks.
The following changes since Linux 2.6.35-rc6 are available in the git
repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/chris/linux-2.6.git lmc
Krzysztof Hałasa (29):
LMC: whitespace and cosmetic fixes.
LMC: Remove "lmc_" prefix from source file names.
LMC: Remove 3 typedefs.
LMC: fix initialization messages.
LMC: Remove non-LMC_PPP modes, everything is already handled by generic HDLC.
LMC: Remove stub files proto.[ch].
LMC: Convert media structs to named initializers.
LMC: Remove "dummy" media functions.
LMC: shuffle protocol routines to avoid a need for prototypes.
LMC: Remove empty media functions.
LMC: Get rid of lmcConsoleLog().
LMC: Get rid of the event logger.
LMC: Get rid of debug.[ch].
LMC: Remove now empty header file lmc.h.
LMC: lanmedia.com is not functional anymore.
LMC: Remove unused macros.
LMC: don't wait in lmc_trace().
LMC: strip "lmc_" prefix from field names in struct card.
LMC: Remove sc->check. We don't do such checks in drivers.
LMC: Remove unused sc->board_idx.
LMC: I'm sure Linux doesn't swap PCI subsystem device and vendor IDs.
LMC: Move model logic to media structs.
LMC: lmc_set_protocol() is effectively a NOP, remove it.
LMC: Remove unused variables.
LMC: Remove unneeded prototypes.
LMC: Remove redundant macro.
LMC: Remove redundant card->name.
LMC: Simplify and fix CSR names and logic.
LMC: Report proper card type before the first dev->open().
