156 * Quoting 10.3.1 Queue Pair and EE Context States:
157 *
158 * Note, for QPs that are associated with an SRQ, the Consumer should take the
159 * QP through the Error State before invoking a Destroy QP or a Modify QP to the
160 * Reset State. The Consumer may invoke the Destroy QP without first performing
161 * a Modify QP to the Error State and waiting for the Affiliated Asynchronous
162 * Last WQE Reached Event. However, if the Consumer does not wait for the
163 * Affiliated Asynchronous Last WQE Reached Event, then WQE and Data Segment
164 * leakage may occur. Therefore, it is good programming practice to tear down a
165 * QP that is associated with an SRQ by using the following process:
166 *
167 * - Put the QP in the Error State
168 * - Wait for the Affiliated Asynchronous Last WQE Reached Event;
169 * - either:
170 * drain the CQ by invoking the Poll CQ verb and either wait for CQ
171 * to be empty or the number of Poll CQ operations has exceeded
172 * CQ capacity size;
173 * - or
174 * post another WR that completes on the same CQ and wait for this
175 * WR to return as a WC;
176 * - and then invoke a Destroy QP or Reset QP.
177 *
178 * We use the second option and wait for a completion on the
ec56dc0b 179 * same CQ before destroying QPs attached to our SRQ.
