+ *
+ * - 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.
