Can you explain how you test this?  Do I need a special AP configuration
to do the test, or is a normal ath10k NIC and hostapd enough?

I can try to reproduce the problem and test the fixes here.

Let me try to reproduce it myself first..that will be the fastest way
for me to fix the problem I think.

Thanks,
