EEDI/AUX
O/I
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 RTL8169S 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.
MDI[0]−
In MDI crossover mode, this pair acts as the BI_DB+/- pair, and
is the receive pair in 10Base-T and 100Base-TX.
