Hi!
TP-Link Archer A6 v2 (US/TW)/C6 v2 (US) got OpenWRT support thanks to @gmtandi's work. I was wondering if devices added to the development version tend to be backported to the stable branch. In this case, I think it should work because the hardware is nearly the same as the TP-Link Archer C6 v2 (EU, RU), which is already supported in the stable version.
