[EricLiu]

Dear all,

Platform : Elkhart Lake (x6425RE)
LAN PHY : Marvell PHY (88E1512) via PSE-RGMII(GBE0 and GBE1)
OS : Ubuntu 20.04 (5.13.0-1008-intel),[iso file name : ubuntu-20.04-desktop-amd64+intel-iot.iso]

The Marvell LAN Phy function doesn't work, even it will make os crash
In dmesg shows the following message:
======================================================================
