I see duplicated messages in -current since some time for RTM_NEWADDR and
RMT_DELADDR too, which causes serious problems for some kind of ip-up scripts.
This needs to be fixed, somehow. I haven't looked at details yet - this started
with a kernel change, but the fix may involve keeping a bit more state in
ifwatchd to filter out the unwanted messages.
