This reports the last enable/disable action actually triggered for this feature, reading noOp if no action has been triggered since the device's last reboot. Because this persists the most recent action across the life of the current boot cycle, it is the object to check, rather than the write-only Action object, to determine what was last requested for this feature, complementing cfcFeatureCtrlLastActionResult which reports whether that action actually succeeded. A feature that shows enable here paired with an actionFailed result in cfcFeatureCtrlLastActionResult tells an admin someone tried to turn the feature on, but that attempt did not actually succeed.
