Local fix
Customer reports that doing: chdev -l entN -a adapter_reset=no where entN is the SEA tends to prevent the DSI.
Problem summary
System crash when VIOS with BACKUP SEA configured over ROCE port is rebooted AND rdma attribute set to "desired" or "required".
Problem conclusion
Code changed to yield RDMA whenever SEA is configured over ROCE port with rdma attribute set to "desired" or "required".
Temporary fix
