SubjectProblem with GVRP on eth while having a bridge
Hello list,

this was tested using vanilla 3.7.6 kernel.

When i add a vlan to an ethernet device supporting gvrp everything is
fine until this ethernet device also had a bridge.

This works fine as long as eth1 is not attached to a bridge.

# ip link add link eth1 name eth1.99 type vlan id 99 gvrp on
# ip link set eth1.99 up

The dynamic VLAN stays up at the switch - no problems.

If eth1 has a bridge the dynamic vlan is created at the switch so the
initial packet was send but it disappears after a few seconds.

Wireshark shows that the kernel has stopped sending GVRP packets. After
adding a bridge to eth1.

Greets,
Stefan
