Why does this have to become a contest of wills where someone wins?  I
wish we could just have a technical discussion and get to the best
solution.  You posted an RFC, and I commented on the parts where I
believe I have some expertise.  We're all on the same side here.

Shirley, I think it would still be useful to run benchmarks of IPoIB
on ehca with Dave's NAPI patches, both V5 that changed the "missed
event" behavior and V6 that didn't.  At least I'm curious to know how
much the difference is.
