Is there a mapping onto an IB ServiceID defined?
We aren't currently using the portmapper to discover the serviceid that the NFS/RDMA server is listening on. Brent Callaghan chose serviceid 2049 as a convenience in Sun's first implementation, and so far it has stuck. Theoretically the server can listen on any endpoint it chooses, this is how NFS/TCP and NFS/UDP work. But typically all servers use the well known port. It's probably a good idea to define a better default mapping.
