>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.
>How-To-Repeat:
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....
