>Description:
Most of today's core switches allready support double tagged ("q-in-q"
by cisco or "nested" by allied telesyn) vlans. With free-bsd machines it
is only possible to use single-tagged vlans. This problem exsits in all
Free-BSD releases.

theoretical example:
ifconfig vlan1 create
ifconfig vlan1 vlan 1 vlandev fxp0
ifconfig vlan2 create
ifconfig vlan2 vlan 2 vlandev vlan 1
>Fix:
we thing if_vlan.c should be modified to accept creation of double vlans and to deny creation of tripple, quad tagged vlans....

 I've seen other requests for double vlans, but why do you want to
 disallow tripple, etc. vlans?  That's more difficult since the problem
 now is that vlans aren't exactly ethernet interfaces so the vlan code
 refuses to connect to them.

 Do you have hardware, i.e., q-in-q capable switched network, to test
 a possible solution?

   Donatas,
 
   you can use ng_vlan(4) for this purpose. Have you tried?

 ng_vlan may be suitable for experimentation but I doubt is very useful in
 a production q-in-q environment.
