NAME         top

       efadv_create_driver_qp - Create EFA specific Queue Pair # SYNOPSIS

              #include <infiniband/efadv.h>

              struct ibv_qp *efadv_create_driver_qp(struct ibv_pd *ibvpd,
                                                    struct ibv_qp_init_attr *attr,
                                                    uint32_t driver_qp_type);

DESCRIPTION         top

       efadv_create_driver_qp() Create device-specific Queue Pairs.

       Scalable Reliable Datagram (SRD) transport provides reliable
       out-of-order delivery, transparently utilizing multiple network
       paths to reduce network tail latency.  Its interface is similar to
       UD, in particular it supports message size up to MTU, with error
       handling extended to support reliable communication.

       driver_qp_type
              The type of QP to be created:

              EFADV_QP_DRIVER_TYPE_SRD: Create an SRD QP.

RETURN VALUE         top

       efadv_create_driver_qp() returns a pointer to the created QP, or
       NULL if the request fails.
