+Description:
+ d3cold_allowed is bit to control whether the corresponding PCI
+ device can be put into D3Cold state. If it is cleared, the
+ device will never be put into D3Cold state. If it is set, the
+ device may be put into D3Cold state if other requirements are
+ satisfied too. Reading this attribute will show the current
+ value of d3cold_allowed bit. Writing this attribute will set
+ the value of d3cold_allowed bit.
