Based on a discontinued GitHub Pull Request by
kuyokushin <codenamezero@protonmail.com>

https://github.com/openwrt/openwrt/pull/2545

NOTE: Netgear R6700 v2 have five clones: R6900 v2, R7450, Nighthawk
AC2400, Nighthawk AC2100 and already added R6800. Rest of them  should
be really easy supportable. Image for R6700v2 should work perfectly with
them. Please refer:
