Hi!

What about 802.1q VLANs encapsulated in another 802.1q VLAN ?

On FreeBSD 8.1 or 9.0-BETA1:

  ifconfig vlan123 create
  ifconfig vlan123 vlandev em0 vlan 123
  ifconfig vlan400 create
  ifconfig vlan400 vlandev vlan123 vlan 400
------
ifconfig: SIOCSETVLAN: Protocol not supported
------

Any ideas ?
