		/*
		 * *** 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.
