Thanks for the patch.

To me, it seems really odd to treat packets with and without an
arbitrary VLAN header the same way.  I could see it if the VLAN header
had VID 0 or 1 or some other specified value, but it seems unusual to
ignore it entirely.  Is this standardized or a de facto standard of some
kind?
