There should be sufficient information in /sys. eg. $ cat /sys/class/net/enp1s0/phydev/phy_id 0x001cc914 So enp1s0 probed a PHY using the ID 0x001cc914. Turn that into binary and you get 0000 0000 0001 1100 1100 1001 0001 0100. Look that up in alias. alias mdio:0000000000011100110010?????????? realtek So you need to realtek PHY driver for my enp1s0.
