- * for a few minutes but when the device is moved away from the AP
- * the average will not decrease fast enough to compensate.

- * rx_percentage = (rx_success * 100) / rx_total

+ * Hardware driver will tune the VGC level during each call
+ * to the link_tuner() callback function. This vgc_level is
+ * is determined based on the link quality statistics like
+ * average RSSI and the false CCA count.
*
- * This value should then be checked to not be greated then 100.
+ * In some cases the drivers need to differentiate between
+ * the currently "desired" VGC level and the level configured
