+IWCONFIG COMMANDS
+========================
+power period
+
+ This command is used to configure the station in deep sleep mode /
+ auto deep sleep mode.
+
+ The timer is implemented to monitor the activities (command, event,
+ etc.). When an activity is detected station will exit from deep
+ sleep mode automatically and restart the timer. At timer expiry
+ (no activity for defined time period) the deep sleep mode is entered
+ automatically.
+
+ Note: this command is for SDIO interface only.
+
+ Usage:
+ To enable deep sleep mode do:
+ iwconfig wlan0 power period 0
+ To enable auto deep sleep mode with idle time period 5 seconds do:
+ iwconfig wlan0 power period 5
+ To disable deep sleep/auto deep sleep mode do:
+ iwconfig wlan0 power period -1
+
