[PATCH] RPC: make sure to get the same local port number when reconnecting
Implement a best practice: if the remote end drops our connection, try to reconnect using the same port number. This is important because the NFS server's Duplicate Reply Cache often hashes on the source port number. If the client reuses the port number when it reconnects, the server's DRC will be more effective. Based on suggestions by Mike Eisler, Olaf Kirch, and Alexey Kuznetsky. Test-plan: Destructive testing. Signed-off-by: Chuck Lever <cel@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
