I understand that this is along the lines of the approach poposed by Jack a
while ago:

https://openib.org/svn/trunk/contrib/mellanox/gen2/patches/mad_rmpp_requester_retry.patch

with the difference that duplicate request detection will be handled by full
GID/TID/class/request/response matching, and not just TID matching.
Right?
