SUNRPC: Use shutdown() instead of close() when disconnecting a TCP socket
By using shutdown() rather than close() we allow the RPC client to wait
for the TCP close handshake to complete before we start trying to reconnect
using the same port.
We use shutdown(SHUT_WR) only instead of shutting down both directions,
however we wait until the server has closed the connection on its side.

I've started testing 2.6.26 + revert. It's been a long while since I
started this process so I'll also have a go at an up to date version.
Cheers,
Ian.
