This looks correct. Please fix and MFC. I haven't merged the kernel changes
to change the type of IFT_ for vlan's yet as I was worried about applications
such as this needing to be updated (such as dhcpd for example). I had thought
that I had not merged the kernel change to 8 though, that it was just in 9?
