It wouldn't work for me since the if_vlan device call the device driver's 
output mechanism direct and the SW input path would ignore handling of VLAN
packets ... or atleast this used to be issues.  My machine's that I needed
this for are patched locally to make it work.

I don't know the current state of this.  It gets to be a bit of
a mess re-injection the packet into the stack on output with loops etc.
The ordering of post netgraph/bridge has some issues.  It probably
should be tagged and use that to prevent loops.
