rdma_post_writev - post an RDMA write work request.

       id          A reference to a communication identifier where the request will be posted.

       context     User-defined context associated with the request.

       sgl         A scatter-gather list of the source buffers of the write.

       nsge        The number of scatter-gather array entries.

       flags       Optional flags used to control the write operation.

       remote_addr The address of the remote registered memory to write into.

       rkey        The registered memory key associated with the remote address.

       Posts a work request to the send queue of the queue pair associated with the rdma_cm_id.  The contents of
       the local data buffers will be written into the remote memory region.

       rdma_post_writev - post an RDMA write work request.

       For  a  list  of  supported  flags,  see  ibv_post_send.  Unless inline data is specified, the local data
       buffers must have been registered before the write is issued, and  the  buffers  must  remain  registered
       until the write completes.  The remote buffers must always be registered.

       Write  operations  may  not  be posted to an rdma_cm_id or the corresponding queue pair until it has been
       connected.

       The user-defined context associated with the write request will be returned to the user through the  work
       completion wr_id, work request identifier, field.

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