Mancera. 9) Remove redundant skb_header_pointer() calls in nft_exthdr for tcp options, from Fernando F. Mancera. 10) Fix conntrack_vrf.sh selftest return value in zone subtest, from Florian Westphal. 11) Restrict raw table in nft_compat to specific family, hook and priority, from Florian Westphal. Prepare the flowtable to support for IPv4 over IPv6 tunneling and vice-versa, this includes 4 patches from Lorenzo Bianconi. 12) Explicitly set inner protocol when popping header, this is not needed for the existing IPIP and IP6IP6 case because skb->protocol remains the same. 13) Simplify tuple tunnel information fill up when parsing outer tunnel IP headers. 14) Add a new encap_proto which determines the outer tunnel protocol family. 15) Prepare flowtable forwarding path to deal with mixed IPv4-IPv6 tunnels.
