				Power State: This 2-bit field is used both to determine the current power state of a function
				and to set the function into a new power state. Supported field values are given below.
				•	00b = D0
				•	01b = Reserved
1:0		RW	00b	•	10b = Reserved
				•	11b = D3 hot
				When the software attempts to write an unsupported, optional state to this field, the write
				operation must complete normally on the bus; however, the data is discarded and no state
				change occurs.
