[PATCH net-next,v3] ipvlan: implement .parse_protocol hook function in ipvlan_header_ops

[Zhengchao Shao]

The .parse_protocol hook function in the ipvlan_header_ops structure is
not implemented. As a result, when the AF_PACKET family is used to send
packets, skb->protocol will be set to 0.
Ipvlan is a device of type ARPHRD_ETHER (ether_setup). Therefore, use
eth_header_parse_protocol function to obtain the protocol.
