+Description:	(RW) Reports the current state of the QAT device. Write to
+		the file to start or stop the device.

+
+		* up: the device is up and running
+		* down: the device is down
+
+
+		It is possible to transition the device from up to down only

+Description:	(RW) Reports the current configuration of the QAT device.
+		Write to the file to change the configured services.
+
+		The values are:
+
+		* sym;asym: the device is configured for running crypto
+		  services
+		* dc: the device is configured for running compression services
+
+		It is possible to set the configuration only if the device
+		is in the `down` state (see /sys/bus/pci/devices/<BDF>/qat/state)
+
+		The following example shows how to change the configuration of
+		a device configured for running crypto services in order to
+		run data compression::
+
+			# cat /sys/bus/pci/devices/<BDF>/qat/state
+			up
+			# cat /sys/bus/pci/devices/<BDF>/qat/cfg_services
+			sym;asym
+			# echo down > /sys/bus/pci/devices/<BDF>/qat/state
+			# echo dc > /sys/bus/pci/devices/<BDF>/qat/cfg_services
+			# echo up > /sys/bus/pci/devices/<BDF>/qat/state
+			# cat /sys/bus/pci/devices/<BDF>/qat/cfg_services
+			dc
+
+		This attribute is only available for qat_4xxx devices.
