[openib-general] RDMA connection and address translation API

Have we agreed that this is the functionality that we should be aiming towards?

>    /* wait for resolution */
>    ib_create_qp(...) /* use device pointer we got from rdma_resolve_address()
>*/

We need to insert in here: 

ib_modify_qp(...);  /* somehow uses address resolution... */
ib_post_recvs(...);

>    rdma_connect(...); /* pass transport address we got from
>rdma_resolve_address() */
>    /* wait for connection to finish... */

Another possibility could be to add a list of receives to rdma_connect().
