Actually I'm beginning to wonder what's going on here.
The IB spec says a "last WQE reached" event is generated when a CQE is
generated for the last WQE. Is this different from the CQE actually
being in the CQ?
This is probably a question for Eli or other Mellanox guys: is it
possible for the driver to see a "last WQE reached" event before all
CQEs are actually visible with mthca HW -- ie is the scenario below with
two QPs attached to an SRQ:
last WQE event for QP A
last WQE event for QP B
post send to QP that will complete with flush err
then poll CQEs and see the send completion from QP A followed by a
receive completion for QP B actually possible?
