158 * Quoting 10.3.1 Queue Pair and EE Context States:
159 *
160 * Note, for QPs that are associated with an SRQ, the Consumer should take the
161 * QP through the Error State before invoking a Destroy QP or a Modify QP to the
162 * Reset State. The Consumer may invoke the Destroy QP without first performing
163 * a Modify QP to the Error State and waiting for the Affiliated Asynchronous
164 * Last WQE Reached Event. However, if the Consumer does not wait for the
165 * Affiliated Asynchronous Last WQE Reached Event, then WQE and Data Segment
166 * leakage may occur. Therefore, it is good programming practice to tear down a
167 * QP that is associated with an SRQ by using the following process:
168 *
169 * - Put the QP in the Error State
170 * - Wait for the Affiliated Asynchronous Last WQE Reached Event;
171 * - either:
172 * drain the CQ by invoking the Poll CQ verb and either wait for CQ
173 * to be empty or the number of Poll CQ operations has exceeded
174 * CQ capacity size;
175 * - or
176 * post another WR that completes on the same CQ and wait for this
177 * WR to return as a WC;
178 * - and then invoke a Destroy QP or Reset QP.
179 *
180 * We use the second option and wait for a completion on the
ec56dc0b 181 * same CQ before destroying QPs attached to our SRQ.
