Hello Eric,

> What is your NIC model and driver?

I have four Intel Corporation I350 Gigabit Network Connection (rev 01).

(node-62) [~/work/linux-2.6] lspci -v | pbot
http://pbot.rmdir.de/rgu6yHMBDVQpflMmbcJACg
(node-62) [~/work/linux-2.6] ip a s | pbot

(node-62) [~/work/linux-2.6] dmesg | pbot
http://pbot.rmdir.de/MigrSPtxGmp0fI1CRgXsHw

I do 802.3ad link aggregation layer 2 hash with two network cards to one
switch.

I'm running:
Linux node-62 3.14.0-rc1+ #23 SMP Sat Feb 8 14:27:47 CET 2014 x86_64 GNU/Linux

Driver: igb

If you need remote access to the machine let me know.

Cheers,
Thomas
