This pin is used to notify the RTL8100C(L) of the existence of Aux.
power (only during initial power-on). This pin should be pulled high
to the auxiliary power (5VPM or 3VAUX) via a resistor to detect the
Aux. power. Doing so will enable wakeup support from ACPI D3
cold or APM power-down. If this pin is not pulled high, the
RTL8100C(L) assumes that no auxiliary power exists.
EEDI: After Aux. Power On Detection is complete; EEDI is enabled
to support EEPROM auto-load operation.
