+Subject: bridge: correct IPv6 checksum after pull
+
+From: stephen hemminger <shemminger@vyatta.com>
+
+commit fa2da8cdae1dd64f78fc915ca1d1a4a93c71e7cb upstream.
+
+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.
