Can't add additional wireless interfaces - QCA9880 (NBG6716 on ath79 snapshot (nov. 26))

Are you using the NBG6716 as an accesspoint or as a router+accesspoint?

The plan is to use it as both, but for now I use it as a secondary router and access point in order to test for stability. I'm thinking about porting the config files to 19.07 and compile it manually, to get a stable version. For some reason they still build it under ar71 instead of ath79, I don't know why.

@glefebvr The PR still hasn't been merged. @kev Are you still compiling your own images to get 2.4Ghz Wifi working?

yep, no choice!

@kev, can you do the following:

ip link show

On the router and tell me how many MAC addresses you have right now with the ath79 version?

With the latest (19.07.2) ar71xx version I have 4, 1x eth0, 1x eth1, 1xwlan0 and 1xwlan1:
eth1 is one higher as eth0
wlan1 is one lower as wlan0

@kev: currently Adrian is creating an appropriate patch, would you please be so kind to test it when it's ready (probably within a few hours) so it can be really fixed in the snapshots?
I believe you have a 128Mb model? See: https://github.com/openwrt/openwrt/pull/2637
