Bug Description

SRU justification:

Impact: Earlier update assigned the wrong values to some registers.

Fix: Simple swap of the assignments (part of stable 2.6.31.5)

--

After I've upgraded kernel to 2.6.31 (Ubuntu build) at my linux-box with Intel 82574L NIC I saw that Jumbo frames doesn't working at all.

# ifconfig eth0 mtu 4000
SIOCSIFMTU: Invalid argument

# lspci | grep Network
02:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection
03:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection

I've figured out that this is a regression comparing to 2.6.28 kernel. So, I've checked e1000e driver that handle 82574L NIC and found a bug. This problem seems to affect only 82574 chip. I wrote patch to fix this bug, it's in attachment.
