Yes, this was what I was reading in a different mail and also the reason
why I've tried to get it working for ath9k<->ath10k. But unfortunately,
I had no success.

I have also tried to use your config without the overrides and with
overrides without any success.

I had to hack a little bit of OpenWrt away but it seems that it works for
a simple setup to first create the adhoc interface and then sometimes later
add the AP interface.

Thanks for your feedback.
