debug tools for mdio

Hi,
is there any debug tools for marvell phy on jetson agx xavier board?
the eth0 link is not up in my board. It seems I need check the mdio registers. However I didn’t found a suitable debug tool.
Could you please recommend one or is there any legacy tool in your release package?
Thanks
