Subject: [PATCH net-next v2 08/15] net: ethernet: mtk_eth_soc: increase DMA ring sizes
Date: Thu, 22 Apr 2021 22:21:01 -0700 [thread overview]
Message-ID: <20210423052108.423853-9-ilya.lipnitskiy@gmail.com> (raw)
In-Reply-To: <20210423052108.423853-1-ilya.lipnitskiy@gmail.com>
From: Felix Fietkau <nbd@nbd.name>
256 descriptors is not enough for multi-gigabit traffic under load on
MT7622. Bump it to 512 to improve performance.
