Is there an way for a program to know when the list of network interfaces has changed (without rescanning them)?

I am cc'ing Michael Tuexen <tuexen at FreeBSD.org>,
both a FreeBSD and long time wireshare developer.

I see there has been at least 2 ways proposed to you for
doing this, I would suggest using the route socket as the
prefered method as that should be some what portable
accross all the BSD type platforms, a devd solution would
be FreeBSD specific.
