       rdma_create_qp - Allocate a QP.


       #include <rdma/rdma_cma.h>

       int  rdma_create_qp  (struct  rdma_cm_id  *id,  struct ibv_pd *pd, struct ibv_qp_init_attr


       id          RDMA identifier.

       pd          Optional protection domain for the QP.

                   Initial QP attributes.


       Allocate a QP associated with the specified rdma_cm_id and transition it for  sending  and


       Returns  0  on success, or -1 on error.  If an error occurs, errno will be set to indicate
       the failure reason.


       The rdma_cm_id must be bound to a local RDMA device before calling this function, and  the
       protection  domain  must  be  for  that  same  device.  QPs allocated to an rdma_cm_id are
       automatically transitioned by the librdmacm through their states.  After being  allocated,
       the  QP will be ready to handle posting of receives.  If the QP is unconnected, it will be
       ready to post sends.

       If a protection domain is not given - pd parameter is NULL - then the rdma_cm_id  will  be
       created using a default protection domain.  One default protection domain is allocated per
       RDMA device.

       The initial QP attributes are specified by the qp_init_attr parameter.   The  send_cq  and
       recv_cq  fields  in  the  ibv_qp_init_attr  are optional.  If a send or receive completion
       queue is not specified, then a CQ will be allocated by the rdma_cm for the QP, along  with
       corresponding completion channels.  Completion channels and CQ data created by the rdma_cm
       are exposed to the user through the rdma_cm_id structure.

       The actual capabilities and properties of the created QP will  be  returned  to  the  user
       through the qp_init_attr parameter.
