136 | * Quoting 10.3.1 Queue Pair and EE Context States: | |
137 | * | |
138 | * Note, for QPs that are associated with an SRQ, the Consumer should take the | |
139 | * QP through the Error State before invoking a Destroy QP or a Modify QP to the | |
140 | * Reset State. The Consumer may invoke the Destroy QP without first performing | |
141 | * a Modify QP to the Error State and waiting for the Affiliated Asynchronous | |
142 | * Last WQE Reached Event. However, if the Consumer does not wait for the | |
143 | * Affiliated Asynchronous Last WQE Reached Event, then WQE and Data Segment | |
144 | * leakage may occur. Therefore, it is good programming practice to tear down a | |
145 | * QP that is associated with an SRQ by using the following process: | |
146 | * | |
147 | * - Put the QP in the Error State | |
148 | * - Wait for the Affiliated Asynchronous Last WQE Reached Event; | |
149 | * - either: | |
150 | * drain the CQ by invoking the Poll CQ verb and either wait for CQ | |
151 | * to be empty or the number of Poll CQ operations has exceeded | |
152 | * CQ capacity size; | |
153 | * - or | |
154 | * post another WR that completes on the same CQ and wait for this | |
155 | * WR to return as a WC; | |
156 | * - and then invoke a Destroy QP or Reset QP. | |
157 | * | |
158 | * We use the second option and wait for a completion on the | |
ec56dc0b | 159 | * same CQ before destroying QPs attached to our SRQ. |
