This code was put into NTP because a number of Operating Systems were not
checking that a source address of ::1 can only come in on the loopback
interface. This code is a workaround for something that should have been in the
O/S kernal. You should be checking the kernel to make sure that the situation
cannot happen in FreeBSD rather than worrying about this fix.
