Hi Lorenzo

There is nothing about MDIO, PHYs, Ethernet switches, etc in version
6.2 of the spec. If x86 has this, it must be after 6.2 was released.
I would not be too surprised if x86 has none of this. If you look at
the typical drives used on x86, i210, e1000e, ixgb, r8169, etc. They
are all PCI devices, and hide all this.

Agreed. Due diligence so far suggests there is nothing already
defined. But im a newbie to ACPI, so could be looking in the wrong
place. I really hope there is somebody like Rob Herring, the DT
maintainer, who keeps an eye on all ACPI talk and would tell us if we
are heading off in the wrong direction.
