> 1. if port-1 fails, four things happen:
>         a). the ongoing rds-rdma message will be reported as RDS_RDMA_REMOTE_ERROR or RDS_RDMA_OTHER, other rdma messages will be dropped;
>         b). IB bonding migrate to port-2;
>         c). RDS re-establish the connection over port-2;
>         d). application re-send the dropped rds-rdma message immediately;
>
