Sure:
# brctl show
bridge name     bridge id               STP enabled     interfaces
vmbr0           8000.00259084dea8       no              bond0

I addd that patch and now the vlan stuff works at least on the host
node. But my tap devices still don't work.

I also tried to attach the tap device on top of a vlan attached to bond1
but then gvrp does not work anymore. The kernel announces gvrp once and
then does not answer the query packets from the switch.
