EEDI: Output to serial data input pin of EEPROM.
AUX: Input pin to detect if Aux. Power exists or not on initial power-on.
This pin should be connected to EEPROM. To support wakeup from ACPI
D3cold or APM power-down, this pin must be pulled high to aux. power via
a resistor. If this pin is not pulled high to Aux. Power, the RTL8110SC(L)
assumes that no Aux. Power exists.

In MDI mode, this is the first pair in 1000Base-T, i.e. the BI_DA+/- pair, and is
the transmit pair in 10Base-T and 100Base-TX.
In MDI crossover mode, this pair acts as the BI_DB+/- pair, and is the receive
pair in 10Base-T and 100Base-TX.
