I also agree that this should sleep for a bit, I do however see a
different use: adding a device to multiple bridges.

(this kinda obviously needs a dynamic priority)

Bridges can filter their RX on everything ebtables can match, they can
even strip off VLAN tags and become "super-VLAN" devices, if you want
that. (Can't access the stripped tag though... but what isn't can
come...)

=46or macvlan/macvtap tbh i try to abstain from using them. Whatever
performance gains/... they give, a setup like
   (eth0-<br0>-veth0)...veth1/tap1=20
appears much cleaner to me.
