Sean, same here, with both 3.2 and 3.3-rc1 I see with tcpdump that no 
GRO aggregation is done in the receiving side, when applying the patch I 
sent (Eric's patch enhanced to change ipoib code such that it sets 
gro_mac_header_lento the ipoib header len), I can see GRO aggregation 
and the performance goes well up. So how do we go from here? Herbert, 
Roland, are you okay with the patch?

Eric, if this we're going on that patch, could you please add 
Reported-by: Shlomo Pongratz <shlomop-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org> to the change-log.

Or.
