It appears the problem is that some ethernet interface has
been created (presumably a VLAN interface), yet ether_ifattach()
was never called..  so ng_ether crashes because there's no
node associated with the interface (which there would be had
ether_ifattach() been called).

Maybe a VLAN expert can shed some light?
