Hi Florian

It took me a while to make this work with CONFIG_BRIDGE_VLAN_FILTERING
enabled. Any change to enable hardware flooding needs careful testing
for lots of different configurations. This is another reason i don't
want to do it at the DSA level, until we have a good understanding
what it means in each individual driver.
