Message-ID: <20231202130658.2266526-1-shaozhengchao@huawei.com> Date: Sat, 2 Dec 2023 21:06:58 +0800 From: Zhengchao Shao <shaozhengchao@...wei.com> To: <netdev@...r.kernel.org>, <davem@...emloft.net>, <edumazet@...gle.com>, <kuba@...nel.org>, <pabeni@...hat.com> CC: <weiyongjun1@...wei.com>, <yuehaibing@...wei.com>, <shaozhengchao@...wei.com> Subject: [PATCH net-next,v2] 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.
