Some NXP MDIO bus master? An XGMAC Ethernet controller which has an NXP MDIO bus master? A cluster of Ethernet controllers? Is this documented somewhere? In the DT world we have a clear documentation for all the compatible strings. Is there anything similar in the ACPI world for these magic numbers? Thanks Andrew
