net: ipip: implement header_ops->parse_protocol for AF_PACKET
Ipip 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 ipip rejects the
skb. So, this wires up the ip_tunnel handler for layer 3 packets for
that case.
