RFC 5666: The "rdma" netid is to be used when IPv4 addressing
is employed by the underlying transport, and "rdma6" for IPv6
addressing.
Add mount -o proto=rdma6 option to support NFS/RDMA IPv6 addressing.
Changes from v1:
- Integrated comments from Chuck Level, Anna Schumaker, Trodt Myklebust
- Add a little more to the patch description to describe NFS/RDMA
IPv6 usage
- Removed duplicated rdma6 define
- Removed Opt_xprt_rdma mountfamily since this doesn't support
