> This set makes the bridge dump host-joined mdb entries, they should be

> We already have notifications for them but we couldn't dump them until
> now so they remained hidden. We dump them similar to how they're
> notified, in order to keep user-space compatibility with the dumped
> objects (e.g. iproute2 dumps mdbs in a format which can be fed into
> add/del commands) we allow host-joined groups also to be added/deleted via
> mdb commands. That can later be used for L2 mcast MAC manipulation as
> was recently discussed. Note that iproute2 changes are not necessary,
> this set will work with the current user-space mdb code.
