+		 * *** The code block below is commented out ***
+		 * Reason: Probably, original Netis N6 EEPROM has wrong
+		 *         MT_EE_WIFI_CONF value 0xd2. As a result 2.4 GHz
+		 *         doesn't start with mt76 driver. Other routers
+		 *         with the same WLAN chips (e.g., Routerich
+		 *         AX1800) have  MT_EE_WIFI_CONF = 0x92.
+		 * Workaround: Extract EEPROM to a file at the first time
+		 *             boot and change MT_EE_WIFI_CONF (offset
+		 *             0x190) value from 0xd2 to 0x92. See
+		 *             /etc/hotplug.d/firmware/11-mt76-caldata for
+		 *             details.
