Linus Lüssing 2cd4143192 bridge: memorize and export selected IGMP/MLD querier port
Adding bridge support to the batman-adv multicast optimization requires
batman-adv knowing about the existence of bridged-in IGMP/MLD queriers
to be able to reliably serve any multicast listener behind this same
bridge.
