Subject: [PATCH net-next 2/4] net: ethernet: mtk_eth_soc: use napi_build_skb()
Date: Tue, 15 Oct 2024 13:09:36 +0200	[thread overview]
Message-ID: <20241015110940.63702-2-nbd@nbd.name> (raw)
In-Reply-To: <20241015110940.63702-1-nbd@nbd.name>

The napi_build_skb() can reuse the skb in skb cache per CPU or
can allocate skbs in bulk, which helps improve the performance.
