I have this issue after updating meta layers to honister and kernel to version 5.10. My problem was fixed by changing fec node in device tree - phy-mode value should be rgmii-id and phy-reset-duration should be increased:

phy-mode = "rgmii-id";
phy-reset-duration = <10>;

You can see at commit logs in imx devicetrees on kernel repository for more information.
