Fixed in 3.1 (and queued for 3.0 stable).
commit fa2da8cdae1dd64f78fc915ca1d1a4a93c71e7cb

bridge: correct IPv6 checksum after pull
Bridge multicast snooping of ICMPv6 would incorrectly report a checksum prob
when used with Ethernet devices like sky2 that use CHECKSUM_COMPLETE.
When bytes are removed from skb, the computed checksum needs to be adjusted.
