Subject: Re: be2net: GRO for non-inet protocols

I got my hands on some new hardware with Intel 82599EB based 10G nics 
(Ixgbe driver)
TIPC GRO works fine with this, the 256b segments sent over a stream connection 
are aggregated together as shown below.

This confirms that the problem is in be2net driver and/or firmware.
