Given that we spoke about this reduction in the number of netlink messages

No, it would be nice to have but as this is just a minor detail and
complexity would be too high I am fine with your current solution.

The end result here is that for listeners on netlink sockets on systems
that (a) have optimistic dad built-in, (b) have optimistic dad enabled, and
(c) have use_optimistic set: they'll 2 notifications (with different flags)
for automatically added addresses on these interfaces.

Ack, I see.

(Personally, given that we appear to send an RTM_NEWADDR when the address
gets deprecated (I think), I think sending one on every flag change of
interest is in keeping with existing behaviour.)

It does make sense, I have no objections.
