136 * Quoting 10.3.1 Queue Pair and EE Context States:
137 *
138 * Note, for QPs that are associated with an SRQ, the Consumer should take the
139 * QP through the Error State before invoking a Destroy QP or a Modify QP to the
140 * Reset State. The Consumer may invoke the Destroy QP without first performing
141 * a Modify QP to the Error State and waiting for the Affiliated Asynchronous
142 * Last WQE Reached Event. However, if the Consumer does not wait for the
143 * Affiliated Asynchronous Last WQE Reached Event, then WQE and Data Segment
144 * leakage may occur. Therefore, it is good programming practice to tear down a
145 * QP that is associated with an SRQ by using the following process:
146 *
147 * - Put the QP in the Error State
148 * - Wait for the Affiliated Asynchronous Last WQE Reached Event;
149 * - either:
150 * drain the CQ by invoking the Poll CQ verb and either wait for CQ
151 * to be empty or the number of Poll CQ operations has exceeded
152 * CQ capacity size;
153 * - or
154 * post another WR that completes on the same CQ and wait for this
155 * WR to return as a WC;
156 * - and then invoke a Destroy QP or Reset QP.
157 *
158 * We use the second option and wait for a completion on the
ec56dc0b 159 * same CQ before destroying QPs attached to our SRQ.
