-	 * Statistics required for Link tuning.
-	 * For the average RSSI value we use the "Walking average" approach.
-	 * When adding RSSI to the average value the following calculation
-	 * is needed:
-	 *
-	 *        avg_rssi = ((avg_rssi * 7) + rssi) / 8;
-	 *
-	 * The advantage of this approach is that we only need 1 variable
-	 * to store the average in (No need for a count and a total).
-	 * But more importantly, normal average values will over time
-	 * move less and less towards newly added values this results
-	 * that with link tuning, the device can have a very good RSSI
-	 * for a few minutes but when the device is moved away from the AP
-	 * the average will not decrease fast enough to compensate.
-	 * The walking average compensates this and will move towards
-	 * the new values correctly allowing a effective link tuning.
+	 * Statistics required for Link tuning by driver
+	 * The rssi value is provided by rt2x00lib during the
+	 * link_tuner() callback function.
+	 * The false_cca field is filled during the link_stats()
+	 * callback function and could be used during the
+	 * link_tuner() callback function.

-	 * Statistics required for Signal quality calculation.
-	 * For calculating the Signal quality we have to determine

-	 * After that we also use the average RSSI value to help
-	 * determining the signal quality.
-	 * For the calculation we will use the following algorithm:
-	 *
-	 *         rssi_percentage = (avg_rssi * 100) / rssi_offset
-	 *         rx_percentage = (rx_success * 100) / rx_total
-	 *         tx_percentage = (tx_success * 100) / tx_total

-	 *                       (WEIGHT_RX * rx_percentage)) / 100
+	 * VGC levels
+	 * 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
+	 * in the hardware. The latter is important to reduce the
+	 * number of BBP register reads to reduce register access
+	 * overhead. For this reason we store both values here.
