> Roland, I think you misunderstand this language. > It simply means that CQEs can disappear if you reset the QP. Yes, _can_ disappear, not _must_ disappear. Which means that CQEs are allowed to be returned after the QP that generated them is gone. In fact the spec's language suggests that the normal situation is for CQEs to stick around after a QP is destroyed, but that the strange behavior (which mthca implements) of CQEs disappearing is also permitted. And in fact if I recall correctly, the Solaris stack goes through some crazy inefficiency exactly so that it can return CQEs for a QP after that QP is destroyed. > If stale CQEs could come out, you would never be able to > destroy a QP without destroying the CQ.
