Subject: Re: IGB driver upgrade

i have tested next configurations for several days:

standalone 2.2.9 driver with 2.6.35-rc4 and RSS=0
standalone 2.2.9 driver with 2.6.33.2 and RSS=0
statically linked driver with 2.6.35-rc4 kernel

all three configurations had no any problems.
seems that IGB was fixed in 35-rc4.

gonna try 2.6.34.1 with static drivers tomorrow night.
