aa20c6c6d2 igb: PCIe devices do not need to unset MANC_ARP_ENA
Users reported that ARP's were lost with igb. The problem
is fixed by not enabling this manageability configuration
bit.

None of the release_manageability code is actually needed as the
normal device reset during a shutdown returns everthing to
the right condition automatically.

41825d7158 ixgbe: Correctly obtain protocol information on transmit
In reply to "RE: [Fwd: [PATCH 2.6.25] ixgbe/igb: correctly obtain protocol
information on transmit]" from Andy Gospodarek:

The driver was incorrectly looking at socket headers for
protocol information, needed for checksumming offload. Fix
this by not looking at the socket but frame headers instead.

This disregards extension headers but it's unclear that linux
generates those anyway.

Tested by Andy Gospodarek.

9f30c768c0 mkiss: ax_bump() locking fix
According to one of OOPSes reported by Jann softirq can break
while skb is prepared for netif_rx. The report isn't complete,
so the real reason of the later bug could be different, but
IMHO this locking break in ax_bump is unsafe and unnecessary.

a1a98b72db Fix station address detection in smc
Megahertz EM1144 PCMCIA ethernet adapter needs special handling
because it has two VERS_1 tuples and the station address is in
the second one. Conversion to generic handling of these fields
broke it. Reverting that fixes the device.

69c3683ca7 netconsole: avoid null pointer dereference at show_local_mac()
This patch avoids a null pointer dereference when we read local_mac 
for netconsole in configfs and shows default local mac address
value.

A null pointer dereference occurs when we call show_local_mac() via 
local_mac entry in configfs before we setup the content of netpoll
using netpoll_setup().

11e75a7455 mlx4_core: Move table_find from fmr_alloc to fmr_enable
mlx4_table_find (for FMR MPTs) requires that ICM memory already be
mapped.  Before this fix, FMR allocation depended on ICM memory
already being mapped for the MPT entry.  If all currently mapped
entries are taken, the find operation fails (even if the MPT ICM table
still had more entries, which were just not mapped yet).

This fix moves the mpt find operation to fmr_enable, to guarantee that
any required ICM memory mapping has already occurred.

This is specifically designed to undo the change in commit
4e4fc05a2b which hardwires the
type for everyone but blackfin to IRQT_RISING, which breaks
all a number of Simtec boards which use (and setup in the
bootloader) active low IRQs.

Note, although there where originally objections due to
the use of IORESOURCE_IRQ and IRQT_ flags not sharing the
same definition, at least <include/linux/interrupt.h> notes
these are the same.

a8cc21f646 Optimize cxgb3 xmit path (a bit)
1. Add common code for stopping queue.
	2. No need to call netif_stop_queue followed by netif_wake_queue (and
	   infact a netif_start_queue could have been used instead), instead
	   call stop_queue if required, and remove code under USE_GTS macro.
	3. There is no need to check for netif_queue_stopped, as the network
	   core guarantees that for us (I am sure every driver could remove
	   that check, eg e1000 - I have tested that path a few billion times
	   with about a few hundred thousand qstops but the condition never
	   hit even once).

3c34ac36ac e1000: Fix for 32 bits platforms with 64 bits resources
The e1000 driver stores the content of the PCI resources into
unsigned long's before ioremapping. This breaks on 32 bits
platforms that support 64 bits MMIO resources such as ppc 44x.

This fixes it by removing those temporary variables and passing
directly the result of pci_resource_start/len to ioremap.

The side effect is that I removed the assignments to the netdev
fields mem_start, mem_end and base_addr, which are totally useless
for PCI devices.

589866f9f1 PS3: gelic: Add support for dual network interface
Add support for dual network (net_device) interface so that ethernet
and wireless can own separate ethX interfaces.

V2
  - Fix the bug that bringing down and up the interface keeps rx
    disabled.
  - Make 'gelic_net_poll_controller()' extern , as David Woodhouse
    pointed out at the previous submission.
  - Fix weird usage of member names for the rx descriptor chain
V1
  - Export functions which are convenient for both interfaces
  - Move irq allocation/release code to driver probe/remove handlers
    because interfaces share interrupts.
  - Allocate skbs by using dev_alloc_skb() instead of netdev_alloc_skb()
    as the interfaces share the hardware rx queue.
  - Add gelic_port struct in order to abstract dual interface handling
  - Change handlers for hardware queues so that they can handle dual
    {source,destination} interfaces.
  - Use new NAPI functions
This is a prerequisite for the new PS3 wireless support.

is no reason to use our own 2-layer page mapping scheme for large
kernel queue buffers on such systems.  Instead, map the page list to a
single virtually contiguous buffer with vmap(), so that can we access

    <4> <0>Kernel panic - not syncing: Fatal exception in interrupt
    <4>

After looking at the code and the dump I think the following scenario
happened: Ifup was running on cpu2 and the interrupt arrived on cpu0.
Now virtnet_open on cpu 2 managed to execute napi_enable and disable_cb
but did not execute rx_schedule. Meanwhile on cpu 0 skb_recv_done was
called by vring_interrupt, executed netif_rx_schedule_prep, which
succeeded and therefore called disable_cb. This triggered the BUG_ON,
as interrupts were already disabled by cpu 2.

I think the proper solution is to make the call to disable_cb depend on
the atomic update of NAPI_STATE_SCHED by using netif_rx_schedule_prep
in the same way as skb_recv_done.

8353ec7b0d cpmac: convert to new Fixed PHY infrastructure
This patch converts cpmac to the new Fixed PHY infrastructure, though it
doesn't fix all the problems with that driver. I didn't even bother to
test this patch to compile, because cpmac driver is broken in several ways:

1. This driver won't compile by itself because lack of its header describing
   platform data;
2. It assumes that fixed PHYs should be created by the ethernet driver.
   It is wrong assumption: fixed PHYs creation is platform code authority,
   driver must blindly accept bus_id and phy_id platform data variables
   instead.

Also, it seem that that driver doesn't have actual in-tree users, so
nothing to fix further.

The main purpose of that patch is to get rid of the following Kconfig
warning:

scripts/kconfig/conf -s arch/powerpc/Kconfig
drivers/net/Kconfig:1713:warning: 'select' used by config symbol
'CPMAC' refers to undefined symbol 'FIXED_MII_100_FDX'

In any error path we must deallocate the DMA frame slots we
previously allocated by request_slot().
This is done by storing the ring pointers before doing any ring
allocation and restoring the old pointers in case of an error.

We must drop any packets we are not able to encrypt.
We must not send them unencrypted or with an all-zero-key (which
basically is the same as unencrypted, from a security point of view).

This might only trigger shortly after resume before mac80211 reassociated
and reconfigured the keys.

It is safe to drop these packets, as the association they belong to
is not guaranteed anymore anyway.
This is a security fix in the sense that it prevents information leakage.

This patch makes suspend/resume work with the b43legacy driver.
We must not overwrite the MAC addresses in the init function, as this
would also overwrite the MAC on resume. With an all-zero MAC the device
firmware is not able to ACK any received packets anymore.
Fix this by moving the initializion stuff that must be done on init but
not on resume to the start function.
Also zero out filter_flags to make sure we don't have some flags
from a previous instance for a tiny timeframe until mac80211 reconfigures
them.

39dbd9587b sky2: fix for Yukon FE (regression in 2.6.25)
The Yukon FE chip has a ram buffer therefore it needs the alignment
restriction and hang check workarounds.

Therefore:
  * Autodetect the prescence/absence of ram buffer
  * Rename the flag value to reflect this
  * Use it consistently (ie don't reread register)

a26af1e08a tun: impossible to deassert IFF_ONE_QUEUE or IFF_NO_PI
From: "Nathaniel Filardo" <nwfilardo@gmail.com>

Taken from http://bugzilla.kernel.org/show_bug.cgi?id=9806

The TUN/TAP driver only permits one-way transitions of IFF_NO_PI or
IFF_ONE_QUEUE during the lifetime of a tap/tun interface.  Note that
tun_set_iff contains

 541         if (ifr->ifr_flags & IFF_NO_PI)
 542                 tun->flags |= TUN_NO_PI;
 543 
 544         if (ifr->ifr_flags & IFF_ONE_QUEUE)
 545                 tun->flags |= TUN_ONE_QUEUE;

This is easily fixed by adding else branches which clear these bits.

Steps to reproduce:

This is easily reproduced by setting an interface persistant using tunctl then
attempting to open it as IFF_TAP or IFF_TUN, without asserting the IFF_NO_PI
flag.  The ioctl() will succeed and the ifr.flags word is not modified, but the
interface remains in IFF_NO_PI mode (as it was set by tunctl).

6e5aa7efb2 virtio: reset function
A reset function solves three problems:

1) It allows us to renegotiate features, eg. if we want to upgrade a
   guest driver without rebooting the guest.

2) It gives us a clean way of shutting down virtqueues: after a reset,
   we know that the buffers won't be used by the host, and

3) It helps the guest recover from messed-up drivers.

So we remove the ->shutdown hook, and the only way we now remove
feature bits is via reset.

We leave it to the driver to do the reset before it deletes queues:
the balloon driver, for example, needs to chat to the host in its
remove function.

3) Rename VIRTIO_NET_F_NO_CSUM to VIRTIO_NET_F_CSUM (ie. means we do
