* Quoting 10.3.1 Queue Pair and EE Context States:
*
* Note, for QPs that are associated with an SRQ, the Consumer should take the
* QP through the Error State before invoking a Destroy QP or a Modify QP to the
* Reset State. The Consumer may invoke the Destroy QP without first performing
* a Modify QP to the Error State and waiting for the Affiliated Asynchronous
* Last WQE Reached Event. However, if the Consumer does not wait for the
* Affiliated Asynchronous Last WQE Reached Event, then WQE and Data Segment
* leakage may occur. Therefore, it is good programming practice to tear down a
* QP that is associated with an SRQ by using the following process:
*
* - Put the QP in the Error State
* - Wait for the Affiliated Asynchronous Last WQE Reached Event;
* - either:
* drain the CQ by invoking the Poll CQ verb and either wait for CQ
* to be empty or the number of Poll CQ operations has exceeded
* CQ capacity size;
* - or
* post another WR that completes on the same CQ and wait for this
* WR to return as a WC;
* - and then invoke a Destroy QP or Reset QP.
*
* We use the second option and wait for a completion on the
* same CQ before destroying QPs attached to our SRQ.
