--- Comment #4 from Rodney W. Grimes <rgrimes at FreeBSD.org> ---
Be aware that vlan tag of 0 is special, it is reserved, and it is reserved for:
The reserved value 0x000 indicates that the frame does not carry a VLAN ID; in
this case, the 802.1Q tag specifies only a priority (in PCP and DEI fields) and
is referred to as a priority tag.
We should be able to match and process these frames, they are standard.
