net: xfrmi: implement header_ops->parse_protocol for AF_PACKET
The xfrm interface uses skb->protocol to determine packet type, and bails out if it's not set. For AF_PACKET injection, we need to support its call chain of: packet_sendmsg -> packet_snd -> packet_parse_headers -> dev_parse_header_protocol -> parse_protocol Without a valid parse_protocol, this returns zero, and xfrmi rejects the skb. So, this wires up the ip_tunnel handler for layer 3 packets for that case. Reported-by: Willem de Bruijn <willemdebruijn.kernel@gmail.com> Signed-off-by: Jason A.
