I think this is what is necessary, please test. Subject: bridge: correct IPv6 checksum after pull
Bridge multicast snooping of ICMPv6 would incorrectly report a checksum problem when used with Ethernet devices like sky2 that use CHECKSUM_COMPLETE. When bytes are removed from skb, the computed checksum needs to be adjusted.
