I don't understand the change. HOST_MDB is used to notify underlying drivers about MDB entries that should be configured to locally receive packets. This is triggered by the transmission of an IGMP report through the bridge, for example. It seems that you're trying to overload HOST_MDB with multicast address filtering on bridge ports? Why are you performing this filtering? Shouldn't you allow all MAC addresses to ingress?
