The Tests uses a small script to loop through the power_state of Dell DW5933e. (for example: /sys/bus/pci/devices/0000\:72\:00.0/power_state) * If Auto suspend is 20 seconds, test script show power_state have 5% of the time was in D3 state when host don't have data packet transmission. * Changed auto suspend time to 5 seconds, test script show power_state have 50% of the time was in D3 state when host don't have data packet transmission.
