Hmm... a tcpdump would help to understand what is going on (for example if GRO kicks in)

I should stop trying to apply patches so late.  I must have done something wrong with my quick test.  Re-applying the patch on 3.2, the ipoib UD performance looks okay to me with Eric's patch.  Sorry about the flub.


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@xxxxxxxxxxxx> to the change-log.

Or.

Or.
