Subject: ar71xx: improve MikroTik wAP R support
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=091e915d994ff77a2677266e9e8cc831a7091deb;p=openwrt%2Fstaging%2Fdedeckeh.git

ar71xx: improve MikroTik wAP R support

81d446b045176e3e25bb0ef74e3d060b51a0a353 introduced incomplete
support for this device.

This patch attempts to correct the situation based on OEM source
code.

LED1-3 are GSM mode on OFW (2G/3G/4G) hence unassigned here.
