Hi Greg Please include commits 70eacf42a93a - arm64: dts: imx8m: correct assigned clocks for FEC 798a1807ab13 - arm64: dts: imx8mp-evk: Improve the Ethernet PHY description in the 5.10.y -stable branch. They fix ethernet on the imx8mp-evk board (the first is relevant for all imx8m boards, but I've only tested on imx8mp-evk). One also needs to have the realtek_phy driver available during early boot (so either built in or as module in initramfs). Upstream has 6937d8c71f69 - arm64: configs: Select REALTEK_PHY as built-in but I'm not sure if such a defconfig change (which affects every arm64 board, as opposed to the much more localized .dts changes) is applicable in -stable. We maintain our own .config anyway, so I don't need 6937d8c71f69 in 5.10-stable. Thanks, Rasmus
