+This target can be used to identify when interfaces have been idle for a
+certain period of time. Timers are identified by labels and are created when
+a rule is set with a new label. The rules also take a timeout value (in
+seconds) as an option. If more than one rule uses the same timer label, the
+timer will be restarted whenever any of the rules get a hit. One entry for
+each timer is created in sysfs. This attribute contains the timer remaining
+for the timer to expire. The attributes are located under the xt_idletimer
+When the timer expires, the target module sends a sysfs notification to the
+userspace, which can then decide what to do (eg. disconnect to save power).
+This is the time in seconds that will trigger the notification.
+This is a unique identifier for the timer.
