We don't really have a good visibility on the number of switches requiring special configuration for broadcast addresses nor how this would have to happen so it would be a tad difficult to define an appropriate API with a single user. In general, single user "generic" facilities tend to be biased towards their particular problem space (c.f: devlink) so a generic interface to call into HW specific details does not usually sell well... -- Florian
