Subject: [PATCH net-next 08/14] net: ethernet: mtk_eth_soc: increase DMA ring sizes
Date: Wed, 21 Apr 2021 21:09:08 -0700	[thread overview]
Message-ID: <20210422040914.47788-9-ilya.lipnitskiy@gmail.com> (raw)
In-Reply-To: <20210422040914.47788-1-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.
