VLAN zero is reserved for usage with priority tagging.  Some people
try to use it as a distinct vlan but it's non-standard and not
consistently supported so I don't think that we should allow it.  Even
with Ben's patch we should never output a packet to vlan zero (outside
of priority tagging), it's just being permissive in what it accepts.
