168 * Quoting 10.3.1 Queue Pair and EE Context States:
169 *
170 * Note, for QPs that are associated with an SRQ, the Consumer should take the
171 * QP through the Error State before invoking a Destroy QP or a Modify QP to the
172 * Reset State. The Consumer may invoke the Destroy QP without first performing
173 * a Modify QP to the Error State and waiting for the Affiliated Asynchronous
174 * Last WQE Reached Event. However, if the Consumer does not wait for the
175 * Affiliated Asynchronous Last WQE Reached Event, then WQE and Data Segment
176 * leakage may occur. Therefore, it is good programming practice to tear down a
177 * QP that is associated with an SRQ by using the following process:
178 *
179 * - Put the QP in the Error State
180 * - Wait for the Affiliated Asynchronous Last WQE Reached Event;
181 * - either:
182 * drain the CQ by invoking the Poll CQ verb and either wait for CQ
183 * to be empty or the number of Poll CQ operations has exceeded
184 * CQ capacity size;
185 * - or
186 * post another WR that completes on the same CQ and wait for this
187 * WR to return as a WC;
188 * - and then invoke a Destroy QP or Reset QP.
189 *
190 * We use the second option and wait for a completion on the
ec56dc0b 191 * same CQ before destroying QPs attached to our SRQ.
