Enabling the auto power-down function on an Ethernet
interface
To save power, enable the auto power-down function on Ethernet interfaces. An interface enters the
power save mode if it has not received any packet for a certain period of time (this interval depends on
the specifications of the chip, and is not configurable). When a packet arrives later, the interface enters
its normal state.
