Have you tested it?
Looks to me like in that case setup_callback_client() will pass
rpc_create() a UDP svc_xprt while requesting protocol
XPRT_TRANSPORT_BC_TCP. Looking down through the code I'm not sure
what's going to happen. I doubt it's good....
So, agreed, making sure we error out in the UDP case (if we don't
already) would be a good idea.
