Hi

That looks interesting. It does not interefere with working code for
Linux or BSD, so we can merge it immediately without much issues. Are
there any significant differenences between Netlink model and BSD kernel?
Like Linux keep (and Netlink API assumes) multiple routes with different
metric, and keeps source protocol.
