222 * Quoting 10.3.1 Queue Pair and EE Context States:
224 * Note, for QPs that are associated with an SRQ, the Consumer should take the
225 * QP through the Error State before invoking a Destroy QP or a Modify QP to the
226 * Reset State. The Consumer may invoke the Destroy QP without first performing
227 * a Modify QP to the Error State and waiting for the Affiliated Asynchronous
228 * Last WQE Reached Event. However, if the Consumer does not wait for the
229 * Affiliated Asynchronous Last WQE Reached Event, then WQE and Data Segment
230 * leakage may occur. Therefore, it is good programming practice to tear down a
231 * QP that is associated with an SRQ by using the following process:
233 * - Put the QP in the Error State
234 * - Wait for the Affiliated Asynchronous Last WQE Reached Event;
236 * drain the CQ by invoking the Poll CQ verb and either wait for CQ
237 * to be empty or the number of Poll CQ operations has exceeded
240 * post another WR that completes on the same CQ and wait for this
241 * WR to return as a WC;
242 * - and then invoke a Destroy QP or Reset QP.
244 * We use the second option and wait for a completion on the
245 * same CQ before destroying QPs attached to our SRQ.
