This would at least activate the old behaviour. But there are also use
cases where you don't want that filtering.

So the problem in my case is that there a some VMs i would like to have
a filter and others where i don't want to have that filter so VLANs
inside the VM are working.

This can again only be archieved by the ebtables filter as it allows us
to control traffic types by VM NIC.
