This patch is to register a callback function tunnel4_rcv_cb with
is_ipip set in a xfrm_input_afinfo object for tunnel4 and tunnel64.
It will be called by xfrm_rcv_cb() from xfrm_input() when family
is AF_INET 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
tunnel4_init/fini(), as Sabrina noticed.
v2->v3:
- Add "#if IS_ENABLED(CONFIG_INET_XFRM_TUNNEL)" to fix the build error
when xfrm is disabled, reported by kbuild test robot.
