ramips: add support for D-Link DIR-853-R1 This PR adds support for router D-Link DIR-853-R1 Specifications: SoC: MT7621AT RAM: 128MB Flash: 16MB SPI WiFi: MT7615DN (2.4GHz+5Ghz) with DBDC (This mode allows this single chip act as an 2x2 11n radio and an 2x2 11ac radio at the same time) LAN: 5x1000M LEDs Power Blue+Orange,Wan Blue+Orange,WPS Blue,"2.4G"Blue, "5G" Blue USB Blue Buttons Reset,WPS, Wifi MAC addresses: |Interface | MAC | Factory |Comment |------------|-----------------|-------------|---------------- |WAN sticker |C4:XX:XX:6E:XX:2A| |Sticker |LAN |C4:XX:XX:6E:XX:2B| | |Wifi (5g) |C4:XX:XX:6E:XX:2C|0x4 | |Wifi (2.4g) |C6:XX:XX:7E:XX:2C| | | | | | | |C4:XX:XX:6E:XX:2E|0x8004 0xe000| | |C4:XX:XX:6E:XX:2F|0xe006 | The increment of the 4th byte for the 2.4g address appears to vary. Reported cases: 5g 2.4g increment C4:XX:XX:6E:XX:2C C6:XX:XX:7E:XX:2C 0x10 f4:XX:XX:16:XX:32 f6:XX:XX:36:XX:32 0x20 F4:XX:XX:A6:XX:E3 F6:XX:XX:B6:XX:E3 0x10 Since increment is inconsistent and there is no obvious pattern in swapping bytes, and the 2.4g address has local bit set anyway, it seems safer to use the LAN address with flipped byte here in order to prevent collisions between OpenWrt devices and OEM devices for this interface. This way we at least use an address as base that is definitely owned by the device at hand. Flashing instruction: The Dlink "Emergency Room" Connect your client computer to LAN1 of the device Set your client IP address manually to 192.168.0.101 / 255.255.255.0. Then, power down the router, press and hold the reset button, then re-plug it. Keep the reset button pressed until the internet LED stops flashing Call the recovery page or tftp for the device at http://192.168.0.1 Use the provided emergency web GUI to upload and flash a new firmware to the device.
