+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.
