when CONFIG_INET is not enabled:
net/xfrm/xfrm_output.c: In function ‘xfrm4_tunnel_encap_add’:
net/xfrm/xfrm_output.c:234:2: error: implicit declaration of function ‘ip_select_ident’ [-Werror=implicit-function-declaration]
ip_select_ident(dev_net(dst->dev), skb, NULL);
XFRM only supports ipv4 and ipv6 so change dependency to INET and place
user-visible options (pfkey sockets, migrate support and the like)
under 'if INET' guard as well.
Fixes: 1de7083006 ("xfrm: remove output2 indirection from xfrm_mode")
