We have this capability already using kqueues, although I'd actually also
like to see a routing socket event.  Somewhere there are dhclient patches
floating around to support kq interface link notifications.  Note that not
all of our supported ethernet interfaces support link state monitoring,
they only have administrative up/down, so any application written to
handle link state information needs to take that into account.
