NFS,RPC: RPC client now advertises maximum payload size
The RPC client now reports the maximum payload size supported by the chosen
transport method. This is something a little less than 64KB for RPC over
UDP, and about 2GB - 1 for RPC over TCP. The effective rsize and wsize
values are not allowed to exceed the reported maximum RPC payload size.
