Subject: Re: Severe regression in bnx2 driver with bonding in post 2.6.30 kernels

Hi Michael,

Thanks for the reply.  When I first became aware of this problem, I checked and applied the most recent Bladecenter/LS21 firmware updates - so the NIC firmware should be current compared to what IBM officially offers.

The ethtool output is:

$ sudo ethtool -i eg0
driver: bnx2
version: 2.0.1
firmware-version: 4.6.1 ipms 1.6.0
bus-info: 0000:02:04.0

The latest IBM firmware update appears to be:

Many thanks,
