Thanks for the clarification. Another question, after the QP entered an
error state, the HCA can generate a cqe for post_send drain WRs?

I saw some panic in Mellanox HCAs, I thought this senarios could cause a
panic. ehca doesn't support post_send() drain WRs after such an event. So
it can't be a problem for ehca.
Since there is no such a post_send() drain WRs for ehca, then we need a
timer value to release the resource from rx_flush_list. Otherwise the
resouces will remain there forever, for a long run, the node loses lots of
memory. We have seen lots of last WQE events when doing interoperability
test between MHCAs and ehcas.
thanks
Shirley
