Dummy Wake-up Sequence
After the OS requests to set the 82559 in the power down state, the driver aborts the receive
activity. Then, the driver loads the required programmable filters to wake-up the system. At this
point, the 82559 is capable of waking up the system if the power management event is enabled.
The driver informs the OS that it may place the 82559 in the power down state. The OS may
proceed with the power down sequence, or it might resume nominal operation. If the 82559 driver
is requested to resume nominal operation, it should follow the same flow as if the 82559 was at the
power down state.
6. The device statistic counters are corrupted during power down state. Therefore, the driver
