157 * Quoting 10.3.1 Queue Pair and EE Context States:
158 *
159 * Note, for QPs that are associated with an SRQ, the Consumer should take the
160 * QP through the Error State before invoking a Destroy QP or a Modify QP to the
161 * Reset State. The Consumer may invoke the Destroy QP without first performing
162 * a Modify QP to the Error State and waiting for the Affiliated Asynchronous
163 * Last WQE Reached Event. However, if the Consumer does not wait for the
164 * Affiliated Asynchronous Last WQE Reached Event, then WQE and Data Segment
165 * leakage may occur. Therefore, it is good programming practice to tear down a
166 * QP that is associated with an SRQ by using the following process:
167 *
168 * - Put the QP in the Error State
169 * - Wait for the Affiliated Asynchronous Last WQE Reached Event;
170 * - either:
171 * drain the CQ by invoking the Poll CQ verb and either wait for CQ
172 * to be empty or the number of Poll CQ operations has exceeded
173 * CQ capacity size;
174 * - or
175 * post another WR that completes on the same CQ and wait for this
176 * WR to return as a WC;
177 * - and then invoke a Destroy QP or Reset QP.
178 *
179 * We use the second option and wait for a completion on the
ec56dc0b 180 * same CQ before destroying QPs attached to our SRQ.
