ok, i'll simplify my question -
 
we have vlan traffic, which is transfered via double tagged vlans (nested 
vlans). Such functions are supported in some advanced switches (AT-8948). The 
problem is - we cannot route those double-tagged vlans using freebsd machines. 
Or maybe it is possible?
let's say we've created vlan-1 and vlan-2, where vlan-2 parent device is vlan-1 
and vlan-1 parent device is physical network adapter. This procedure seems 
impossible in freebsd.
I've mentioned netgraph only as possible solution. Interesting, what happens 
when freebsd get's double-tagged frame?

thank you
