>From the README:

  nmrpflash uses Netgear's NMRP protocol to flash a new firmware image
  to a compatible device.  It has been successfully tested with
  various models (D7000, DNG3700v2, EX2700, EX6100v2, EX6120,
  EX6150v2, EX8000, R6020, R6080, R6100, R6220, R6400, R7000, R7000P,
  R6800, R8000, R8000P, R8500, WAX202, WNDR3800, WNDR4300, WNDR4500v3,
  WNDR4700, WNR3500), but is likely to be compatible with most other
  Netgear devices as well.
