| |
Hello all,
I try to do a setup with qemu and tap devices attached to bridges where 802.1Q vlan packets that are tag stacked are running through the tap device/bridge where the outer tag is stripped. But it seems on the way back out of qemu/guest and back through the tap and bridge no additional vlan tags are added back. The very same setup with only one vlan tag that is stripped and added back works as expected. Is there something in the tap device or bridge code that prevents stacking? Can this be done by configuration or by additional coding in the tap or bridge?
-- Regards, Stephan
