From fa2da8cdae1dd64f78fc915ca1d1a4a93c71e7cb Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Tue, 15 Nov 2011 08:09:14 +0000 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. Signed-off-by: Stephen Hemminger Tested-by: Martin Volf Signed-off-by: David S.
