This series from Danit and Yossi enables application control in some flows as follows. It exposes the internal function 'rdma_init_qp_attr' as an external librdmacm API. As such an application can get the parameters for creating AH (needed for DC QP), or control QP attributes after its creation. In addition, it exposes CONNECT_RESPONSE event and rdma_establish() API. Applications which do not create a QP through rdma_create_qp() may want to postpone the ESTABLISHED event on the passive side, to let the active side complete an application-specific connection establishment phase. For example, modify a QP created by the application to RTR, or make some preparations for receiving messages from the passive side.
