xfrm: choose protocol family by skb protocol
We need to choose the protocol family by skb->protocol. Otherwise we call the wrong xfrm{4,6}_local_error handler in case an ipv6 sockets is used in ipv4 mode, in which case we should call down to xfrm4_local_error (ip6 sockets are a superset of ip4 ones). We are called before before ip_output functions, so skb->protocol is not reset. Cc: Steffen Klassert <steffen.klassert@secunet.com> Acked-by:Eric Dumazet <edumazet@google.com> Signed-off-by:
