Jeffrey, thanks for your report, can you be a little more verbose here
and elaborate as to what you mean by this? Do you mean that you stop
hostapd or that it hostapd is still running and that somehow you
notice it stops sending data between its associated STAs?

This would be from:

        /*
         * The same happens when we're not even started,
         * but that's worth a warning.
         */
        if (WARN_ON(!local->started))
                goto drop

So somehow the RX tasklet kicked in and ath9k RX engine was still running.
