Hi Stephen, Can we rename this flag BRIDGE_IGMP_SNOOPING into something like BRIDGE_MULTICAST_SNOOPING/BRIDGE_MCAST_SNOOPING? I am starting this thread because this BRIDGE_IGMP_SNOOPING flag holds information about IGMP only but not about MLD. Or this is not a common name to describe both IGMP and MLD. Please let me know about my concern, so that I can change the code and submit a patch. Thanks, UjjaL Roy
