Log message:
Do not treat loopback interfaces as p2p interfaces and create only
one route to "::1".
Due to a clever BSD trick, the `ifa_dstaddr` field of addresses on
IFF_LOOPBACK ifps is set to the same value that `ifa_addr`. That's
why filtering for broadcast addresses is so complicated, because
guess what, `ifa_broadaddr` is the same as `ifa_dstaddr`!
Sadly our IPv6 code was "only" checking for `ifa_dstaddr` without
looking if the ifa was attached to a IFF_POINTOTPOINT interface.
So it always tried to create two routes to "::1" and, with the
recent RTF_LOCAL work, succeed.
You should now have only one local route to "::1".
::1 ::1 UHl 14 0 32768 1 lo0
-::1 ::1 UH 0 0 32768 4 lo0
