Joseph Huang 7b0d423183 net: bridge: Do not offload IGMP/MLD messages ... [ Upstream commit 683dc24da8 ] Do not offload IGMP/MLD messages as it could lead to IGMP/MLD Reports being unintentionally flooded to Hosts. Instead, let the bridge decide where to send these IGMP/MLD messages. Consider the case where the local host is sending out reports in response to a remote querier like the following: mcast-listener-process (IP_ADD_MEMBERSHIP) \ br0 / \ swp1 swp2 | | QUERIER SOME-OTHER-HOST In the above setup, br0 will want to br_forward() reports for mcast-listener-process's group(s) via swp1 to QUERIER; but since the source hwdom is 0, the report is eligible for tx offloading, and is flooded by hardware to both swp1 and swp2, reaching SOME-OTHER-HOST as well. (Example and illustration provided by Tobias.)
