This looks good.  With the addition of a way to set a global default, I
think it would satisfy everybody who has asked for this kind of thing in
the past.  (I'd usually want default=common-prefix-len.)

However, I don't like having inteface names (like "ath0") at the same
level of the sysctl name tree as other stuff (like "forwarding",
"redirect", "ttl").  I suggest something like this:

	net.inet.ip.selectsrc.${ifname}
	net.inet.ip.selectsrc.default

or like this:

	net.inet.ip.interfaces.${ifname}.selectsrc
	net.inet.ip.interfaces.default.selectsrc
