This patch fixes "kernel: raw v6 hw csum failure." messages.
It distracted me from the TCPMSS issue, I'll take care of that
tomorrow.
[IPV6]: Fix raw socket hardware checksum failures
When packets hit raw sockets the csum update isn't done yet, do it manually.
Packets can also reach rawv6_rcv on the output path through
ip6_call_ra_chain, in this case skb->ip_summed is CHECKSUM_NONE and this
codepath isn't executed.
