From cb297cc5e194a2ea3cb8aaf722005286ee42b011 Mon Sep 17 00:00:00 2001 From: Zhengchao Shao Date: Sat, 2 Dec 2023 21:06:58 +0800 Subject: macvlan: implement .parse_protocol hook function in macvlan_hard_header_ops The .parse_protocol hook function in the macvlan_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. Macvlan is a device of type ARPHRD_ETHER (ether_setup). Therefore, use eth_header_parse_protocol function to obtain the protocol.
