This only applys to bridge that is blindly bridging without any knowledge
of vlan's. You can already handle the case of bridging selected vlan's
if you tell the kernel about them.

People do it all the time without patch by configuring the vlan's
first then bridging the vlan's.

Not if you bridge the vlan's
