From: Xin Long <lucien....@gmail.com> Date: Sat, 8 Sep 2018 18:15:12 +0800The function csum_ipv6_magic doesn't convert len and proto to big endian before doing ipv6 csum hash, which is not consistent with RFC and other arches. Jianlin found it when ICMPv6 packets from other hosts were dropped in the powerpc64 system. This patch is to fix it by using instruction 'lwbrx' to do this conversion in powerpc32/64 csum_ipv6_magic.

I submitted an alternative fix, and Lucien Xin gave its Tested-by: See https://patchwork.ozlabs.org/patch/967868/ Christophe
