mediatek/filogic: add support for COMFAST CF-XR186 The COMFAST CF-XR186 is a WiFi repeater. The original OEM firmware is a fork of OpenWrt 21.02. To replace the OEM firmware with OpenWrt, flash the sysupgrade image through the firmware upgrade option via the OEM firmware's web UI. The OEM firmware upgrade page does not provide an option to perform a factory reset, so after the flash completes and the device reboots, perform a reset by holding in the WPS/Reset button until the WiFi LED flashes red. The led-boot, led-failsafe, led-upgrade, and led-running aliases all point at the red WLAN GPIO LED. The green and blue WLAN GPIO LEDs are used to indicate activity on the 2.4GHz and 5GHz radios. 01_leds assigns netdev triggers for those LEDs to phy0-ap0 and phy1-ap0 respectively; if neither AP interface exists (e.g. station-only repeater setups), both LEDs stay dark even when WiFi traffic is flowing.
