The ar9331 switch is not forwarding IGMP and MLD packets if IGMP

same decisions as this switch would do to be able to tell the linux
bridge if some packet was prabably forwarded or not.

I am not familiar with IGMP/MLD, therefore I don't really understand
what problem you are trying to solve.

Your switch has packet traps for IGMP and MLD, ok. So it doesn't forward
them. Must the IGMP/MLD packets be forwarded by an IGMP/MLD snooping
bridge? Which ones and under what circumstances?
