 `nmrpflash` uses Netgear's [NMRP protocol](https://web.archive.org/web/www.chubb.wattle.id.au/PeterChubb/nmrp.html)
 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,
