Actually, I take that back.  Every driver seems to set wc->qp in all
cases, so I guess it is safe to rely on that now.  (Which actually
means that the table of RX QPs in the non-SRQ patch can be dropped so
we make things dramatically simpler).

But that means I really have no idea what your bug is.  Could you say
how you're running netperf so I can try to reproduce the crash?
