* In the pre-IPv6 code, secure RPC has a bug such that it doesn't look
* at the endpoint 'family' field when selecting an endpoint to use for
* time synchronization. In order to protect that broken code from itself,
* we set the endpoint 'proto' to 'nc_netid' (i.e., "udp6" or "tcp6")
* rather than 'nc_proto' ("udp"/"tcp") if 'nc_family' is "inet6".
*
* The __nis_netconfig2ep() and __nis_netconfig_matches_ep() service
* functions below simplify endpoint manipulation by implementing the
* rules above.
