Could you please provide full hostapd configuration that can trigger
this and a debug log showing this? In particular, I'd like to understand
which country code was used.  This did not seem to show any issues in a
hwsim test setup with country code US, and I'd like to be able to add a
regression test case with this type of fixes.
