Subject: [PATCH net-next 04/10] net: mediatek: do not assume mac header is set in mtk_start_xmit()
Date: Wed, 2 Sep 2026 00:33:38 +0000 [thread overview]
Message-ID: <20260902003344.1931843-5-edumazet@google.com> (raw)
In-Reply-To: <20260902003344.1931843-1-edumazet@google.com>
We should not assume mac header is set in output path.
Use skb_eth_hdr() instead of eth_hdr() to fix the issue.
