pub(super) fn drop_udp_duplicates(instances: &mut HashMap<String, LanInstance>)Expand description
Remove UDP-learned entries that an mDNS entry now covers (the same address
and port). Called after an mDNS resolution so the order the two routes find a
peer in does not decide whether it is listed twice. Instance ids are not
compared: they are per release, not per machine (see udp_key).
