ote:
At a time, only one MDIO mode is supported. Two different cables are
provided for normal MDIO and easy MDIO respectively. For normal MDIO, current
MDIO cable (FSP12AMS) can be used.
Cable data
Preferably stranded 24 AWG (0.20 mm²) to 20 AWG (0.51 mm²) wires with proper
insulation should be used.
