Subject: ar71xx: add model detection for UBNT AC-Mesh
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=f8dbafb234c9a0a836ff3bede0540c20914b6d4e;p=openwrt%2Fstaging%2Fadrian.git

ar71xx: add model detection for UBNT AC-Mesh

This commit adds correct model detection for UniFi
AC-Mesh. Previously said device was incorrectly detected
as UniFi AC-Lite.

The Information about the device is stored at 0xC in the EEPROM
partition. It corresponds to the sysid in /etc/board.info of the
Ubiquiti stock firmware.
