Subject: [PATCH net-next 1/2] arm64: dts: imx8mp-evk: configure multiple queues on eqos
Date: Wed, 1 Dec 2021 09:47:04 +0800 [thread overview]
Message-ID: <20211201014705.6975-2-xiaoliang.yang_1@nxp.com> (raw)
In-Reply-To: <20211201014705.6975-1-xiaoliang.yang_1@nxp.com>
Eqos ethernet support five queues on hardware, enable these queues and
configure the priority of each queue. Uses Strict Priority as scheduling
algorithms to ensure that the TSN function works.
