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

broke it. Reverting that fixes the device.

Use the flags in the IRQ resource to specify the type of
IRQ being requested, so that systems which do not have

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.
