Every time on boot, I'm seeing messages like:

	wm0: link state changed to DOWN
	wm0: link state changed to UP

for any interface that's used, and just a

	re0: link state changed to DOWN

or similar for any interface that isn't used.

Other than being somewhat annoying, do they serve any useful
purpose?  If there any problem if "#ifdef DEBUG"ing them in
if_link_state_change()?

Simon.
