netfilter: flowtable: populate tunnel tuple regardless of inner protocol
Store the outer tunnel addresses and inner protocol in the flow tuple
unconditionally in nf_flow_tuple_encap(), instead of only when the
tunnel is IP-in-IP or IPv6-in-IPv6. Bail out early when the inner
protocol is neither IPPROTO_IPIP nor IPPROTO_IPV6.
This makes the tuple usable for cross-family tunnels such as
IPv4-over-IPv6 and SIT, where the inner protocol differs from the
outer address family.
This is a preliminary patch to support IPv4 over IPv6 and SIT tunnel
flowtable offload.
Please note IPv4 over IPv6 and SIT tunnel flowtable offloading is not
enabled yet.
