WEBMay 23, 2023 · A queue pair is bound to an rdma_cm_id after calling rdma_create_ep or rdma_create_qp, if the rdma_cm_id is allocated using rdma_create_id. The user-defined context associated with the receive request will be returned to the user through the work completion request identifier (wr_id) field.
