However, in the case of MAC devices where you might need to specify just
a couple of properties using _DSD, a specific set of discussions has
been instigated. As you mentioned, though, this pertains only to certain
devices and isn't necessarily true for every Ethernet device.
Consequently, while a Juno PoC patch might use a kludge today, that
doesn't mean it's a limitation of ACPI, just of certain devices.
Jon.
