WIP: kirkwood: add support for Linksys E4200 (v2)

[GoliathLabs]

• must be flashable from vendor firmware

  • webinterface
  • tftp
  • other:

• must support upgrade mechanism

  • must have working sysupgrade
    • must keep/forget configuration (if applicable)
      think sysupgrade [-n] or firstboot
  • must have working autoupdate
    usually means: gluon profile name must match image name

• reset/wps/phone button must return device into config mode

• primary mac should match address on device label (or packaging) (https://gluon.readthedocs.io/en/latest/dev/hardware.html#notes)

• wired network

  • should support all network ports on the device
  • must have correct port assignment (WAN/LAN)

• wifi (if applicable)

  • association with AP must be possible on all radios
  • association with 802.11s mesh must be working on all radios
  • ap/mesh mode must work in parallel on all radios

• led mapping

  • power/sys led (critical, because led definitions are setup on firstboot only)
    • lit while the device is on
    • should display config mode blink sequence
      (https://gluon.readthedocs.io/en/latest/features/configmode.html)
  • radio leds
    • should map to their respective radio
    • should show activity
  • switchport leds
    • should map to their respective port (or switch, if only one led present)
    • should show link state and activity

• outdoor devices only

  • added board name to is_outdoor_device function in package/gluon-core/luasrc/usr/lib/lua/gluon/platform.lua

  Yet the networking doesn't seem to work quite right. We're currently investigating.
