Andy, while you are testing it, can you ensure it also works for the following setup?

eth0 -> bond0 -> br0 -> br0.100

I think it should, as long as the slave is the first device in the path.

Can you imagine a bonding setup where the slaves are not first in the path?

eth0 -> br0 -> bond0?
eth0 -> eth1(macvlan) -> bond0?
eth0 -> eth0.100 -> bond0?

	Nicolas.
