SUNRPC: Introduce transport switch callout for pluggable rpcbind
Introduce a clean transport switch API for plugging in different types of
rpcbind mechanisms. For instance, rpcbind can cleanly replace the
existing portmapper client, or a transport can choose to implement RPC
binding any way it likes.
Test plan:
Destructive testing (unplugging the network temporarily). Connectathon
with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked.
Probably need to rig a server where certain services aren't running, or
that returns an error for some typical operation.
