From: Michael J. Ruhl <michael.j.ruhl@xxxxxxxxx> When debugging issues with RC QPs, it is useful to know if a QP has an associated RQ or SRQ, the size of the RQ, and any RNR timeout values. Add the necessary information to the QP stats output. Reviewed-by: Mike Marciniszyn <mike.marciniszyn@xxxxxxxxx> Signed-off-by: Michael J.
