<p>Hello Tziporet,<br>
<br>
Eli has reviewed the IPoIB-UD 4K mtu patchset. He suggested an alternative way (reserve one buffer for all header including GRH, IPoIB-ethernet, IP header, TCP header, and leave the user data in other buffer) for the implementation but This approach can't avoid if condition check without changing IPoIB-2K MTU implementation. And I am not sure whether or how much performance gain from this approach, it's pretty risky to change IPoIB-2K MTU at this moment. <br>
<br>
I would like to keep my approach, and will limit to one "if need-S/G check" in fast path. and I have passed stress test for both mthca and ehca in the past few days. I don't see any issues for OFED-1.3 RC3. Do you agree to include this IPoIB-UD 4K MTU patch into OFED-1.3 RC4? I need to regerate this patch today since Eli's small messages size patch has been in Git tree.<br>
<br>
Thanks<br>
