Installation
------------
Flash OpenWrt 'sysupgrade.bin' image using stock firmware web-interface
(without keeping settings).

Return to stock
---------------
Install stock firmware image (without keeping settings) using OpenWrt
sysupgrade method.

Recovery
--------
Connect uart, use u-boot menu to flash stock firmware image or boot
OpenWrt initramfs image.

MAC addresses
-------------
+---------+-------------------+-----------+
|         | MAC               | Algorithm |
+---------+-------------------+-----------+
| WAN     | 24:0f:5e:xx:xx:08 | label     |
| LAN     | 24:0f:5e:xx:xx:09 | label+1   |
| WLAN 2g | 24:0f:5e:xx:xx:0a | label+2   |
| WLAN 5g | 24:0f:5e:xx:xx:0b | label+3   |
+---------+-------------------+-----------+
The WLAN 2g MAC was found in 'Factory', 0x4
