[pve-devel] [PATCH] support QinQ / vlan stacking

[Andrew Thrift]

We have found you need to nest the bridges to get QinQ to work in all
scenarios.
e.g. The above patch will work for MOST scenarios, but if you attach a vlan
aware VM to the parent vmbr0 bridge it will cause traffic to the VM's to
stop, or will not be able to see the tagged frames.

The patch we use only has one other minor change:

-        activate_bridge_vlan_slave($bridgevlan, $iface, $tag);
+        activate_bridge_vlan_slave($bridgevlan, $bridge, $tag);
