Subject: [PATCH] arm64: dts: imx8mp-beacon: Configure multiple queues on eqos
Date: Sun, 11 Feb 2024 07:55:34 -0600
Message-ID: <20240211135535.68516-1-aford173@gmail.com>

The imx8mp-beacon SOM has an integrated PHY connected to
the EQOS ethernet controller which can support up to five
queues.  Configure these queues in the same manor as done
on the imx8mp-evk.
