Subject: [PATCH net-next 3/3] rxrpc: Allow multiple client connections to the
 same peer

Allow the number of parallel connections to a machine to be expanded from a
single connection to a maximum of four.  This allows up to 16 calls to be
in progress at the same time to any particular peer instead of 4.
