| 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 |
| class: |
| .PP |
| /sys/class/xt_idletimer/timers/<label> |
| .PP |
| 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). |
| .TP |
| \fB\-\-timeout\fP \fIamount\fP |
| This is the time in seconds that will trigger the notification. |
| .TP |
| \fB\-\-label\fP \fIstring\fP |
| This is a unique identifier for the timer. The maximum length for the |
| label string is 27 characters. |
| .TP |
| \fB\-\---send_nl_msg\fP |
| Send netlink messages in addition to sysfs notifications and show remaining |
| time. |
