ath79: add support for Comfast CF-EW72 Specifications: Qualcomm/Atheros QCA9531 + QCA9886 2x 10/100 Mbps Ethernet, with 48v PoE 2T2R 2.4 GHz, 802.11b/g/n 2T2R 5 GHz, 802.11a/n/ac 128MB RAM 16MB SPI Flash 4x LED (Always On Power, LAN, WAN, WLAN) Flashing Instructions: Original firmware is based on OpenWRT, so flashing the sysupgrade image on the factory firmware is sufficient. Tested: Reset button, WAN LED, LAN LED, Power LED (always on, not much to test), WLAN LED (one LED only for 2 interfaces, by default it gets assigned to the first interface), MAC addresses (match factory firmware). My LAN factory MAC address ends in F2. use stock_mac art_loc lan :f2 0x0 wan :f3 0x1002 5g :f4 0x6 2g :f5 0x5006 Since MAC address flash locations do not really match their use in vendor firmware (e.g. address from 5 GHz calibration data is assigned to 2.4 GHz WiFi), just calculate the MAC addresses with an offset based on 0x0 address.
