I agree that a "broken by default" in OpenWRT/LEDE for a variety of Broadcom devices is not really acceptable. Technically we could teach netifd in OpenWRT/LEDE to configure ebtables accordingly, at least for a list of affected devices, so that users would not have to. However, as ebtables is not managed by the fw3 in OpenWRT/LEDE, that would probably interfer with user provided ebtables rules and scripts... > That said I think we still should look for a solution for existing > firmwares.

Hm, we could change the default in OpenWRT/LEDE for multicast-to-unicast (or more precisely bridge hairpinning) to disabled again for now.
