186 | * Quoting 10.3.1 Queue Pair and EE Context States: | |
187 | * | |
188 | * Note, for QPs that are associated with an SRQ, the Consumer should take the | |
189 | * QP through the Error State before invoking a Destroy QP or a Modify QP to the | |
190 | * Reset State. The Consumer may invoke the Destroy QP without first performing | |
191 | * a Modify QP to the Error State and waiting for the Affiliated Asynchronous | |
192 | * Last WQE Reached Event. However, if the Consumer does not wait for the | |
193 | * Affiliated Asynchronous Last WQE Reached Event, then WQE and Data Segment | |
194 | * leakage may occur. Therefore, it is good programming practice to tear down a | |
195 | * QP that is associated with an SRQ by using the following process: | |
196 | * | |
197 | * - Put the QP in the Error State | |
198 | * - Wait for the Affiliated Asynchronous Last WQE Reached Event; | |
199 | * - either: | |
200 | * drain the CQ by invoking the Poll CQ verb and either wait for CQ | |
201 | * to be empty or the number of Poll CQ operations has exceeded | |
202 | * CQ capacity size; | |
203 | * - or | |
204 | * post another WR that completes on the same CQ and wait for this | |
205 | * WR to return as a WC; | |
206 | * - and then invoke a Destroy QP or Reset QP. | |
207 | * | |
208 | * We use the second option and wait for a completion on the | |
ec56dc0b | 209 | * same CQ before destroying QPs attached to our SRQ. |
