H A Dtunnel6.c86afc703 Mon Jul 06 07:01:31 CDT 2020 Xin Long <lucien.xin@gmail.com> tunnel6: add tunnel6_input_afinfo for ipip and ipv6 tunnels

This patch is to register a callback function tunnel6_rcv_cb with
is_ipip set in a xfrm_input_afinfo object for tunnel6 and tunnel46.

It will be called by xfrm_rcv_cb() from xfrm_input() when family
is AF_INET6 and proto is IPPROTO_IPIP or IPPROTO_IPV6.

v1->v2:
- Fix a sparse warning caused by the missing "__rcu", as Jakub
noticed.
- Handle the err returned by xfrm_input_register_afinfo() in
tunnel6_init/fini(), as Sabrina noticed.
v2->v3:
- Add "#if IS_ENABLED(CONFIG_INET6_XFRM_TUNNEL)" to fix the build error
when xfrm is disabled, reported by kbuild test robot
