[openib-general] [PATCH/RFC 1/2] IB: Return "maybe_missed_event" hint from ib_req_notify_cq()

[Shirley Ma]

Thanks Michael for all these tips. I have tried several suggestions as you
proposed here. I couldn't see performance any better. The TCP_RR is dropped
to 472 trans/s from about 18,000 trans/s , and TCP_STREAM BW is dropped to
1/3 as before ( ehca + scaling code) with same TCP configuration, send
queue size=recve queue size = 1K.

Thanks
