[LEDE-DEV] [PATCH] ar71xx: add Engenius ENH200EXT support

Paul Oranje por at xs4all.nl
Fri Mar 31 13:38:39 PDT 2017 

This POE access point suited for outside usage needs an external antenna.
According FCC documentation the ENH200EXT (needs external antenna) and the ENH200 (with internal antenna) are electrically equal to the Allnet ALL0258N.

The stock image does not allow install of a LEDE factory image, but an initramfs image (lede-ar71xx-generic-enh200ext-initramfs-uImage.bin) can be loaded via u-boot recovery procedure (long press reset at power-on until all LEDS burn). The u-boot recovery procedure boots an image named vmlinux-art-ramdisk from 192.168.1.101.
Once booted the sysupgrade image can be flashed from the booted iniramfs LEDE.

Only abnormality is that for some unknown reason the txpower cannot be set higher than 16 dBm whereas the Engenius stock firmware allows a maximum of 27 dBm.
