Apparently it's experiencing timeouts, I usually get these:

re0: link state changed to DOWN
re0: watchdog timeout
re0: 3 link states coalesced
re0: link state changed to UP
re1: link state changed to DOWN

I've been running all tests under RELENG_7, btw.  Note also, these
delays don't always happen, in some cases the interfaces react very
quickly.  In rare cases, they don't work at all, until you manually
ifconfig down and up them a few times.

What's funny though, is that the interfaces seem to start in DOWN mode:

and only then do they "really" go up... :)

Do you have any good suggestions on where I could put some debug
printfs in re to find out what it's timing out on?

Plugging/unplugging the cable doesn't seem to make much difference, and
neither does disabling WOL before shutdown (or altogether)...
