I'm not sure if this is relevant to the discussion, but I have a wm(4)
device (8086:1502) on -current that does not work after boot. It comes
to life only after running "tcpdump -n -i wm0" once. I am using vlan(4),
but haven't checked if that makes any difference. I usually run the
tcpdump command then forget about it until the next reboot.
