rdma_migrate_id - Move a communication identifier to a different event channel.

       id          An existing communication identifier to migrate.

       channel     The  communication  channel  that  events  associated  with  the allocated rdma_cm_id will be
                   reported on.  May be NULL.

       Migrates a communication identifier to a different event channel.

       rdma_migrate_id - Move a communication identifier to a different event channel.

       This  routine  migrates  a  communication identifier to the specified event channel and moves any pending
       events associated with the rdma_cm_id to the new channel.  Users  should  not  poll  for  events  on  the
       rdma_cm_id's  current  event  channel  or invoke other routines on the rdma_cm_id while migrating between
       channels.  This call will block while there are any unacknowledged events on the current event channel.

       If the channel parameter is NULL, the specified rdma_cm_id will  be  placed  into  synchronous  operation
       mode.  All calls on the id will block until the operation completes.

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