Miller" The multicast optimizations in batman-adv are yet only usable and enabled in non-bridged scenarios. To be able to support bridged setups batman-adv needs to be able to detect IGMP/MLD queriers and reports on mesh nodes without bridges, too. See the following link for details: http://www.open-mesh.org/projects/batman-adv/wiki/Multicast-optimizations-listener-reports To avoid duplicate code between the bridge and batman-adv, the IGMP/MLD message validation code is moved from the bridge to the IPv4/IPv6 stack. On the way, some refactoring to increase readability and to iron out some subtle differences between the IGMP and MLD parsing code is done. Cheers, Linus Changelog v3: * changed interface / restructuring of skb_checksum_trimmed() * kernel doc for skb_checksum_trimmed()/skb_checksum_maybe_trim() * fixed a memory leak in the cloned skb case in skb_checksum_trimmed() * fixed transport_len calculation in __ipv6_mc_check_mld(), make it relative to the skb transport header offset (= exclude the hop-by-hop option size in transport_len) Changelog v2: * Updated copyright for mcast_snoop.c
