It seems like it also happens after 3900 seconds with PSK. So following
config will also create this problem:
driver=nl80211
logger_syslog=127
logger_syslog_level=0
logger_stdout=127
logger_stdout_level=0
country_code=US

wpa_key_mgmt=WPA-PSK
okc=0
disable_pmksa_caching=1
bssid=f8:d9:b8:2e:37:d0
And this problem is trivial to see on the AP (with a single client) using the
following patch:
diff --git a/drivers/net/wireless/ath/ath11k/wmi.c b/drivers/net/wireless/ath/ath11k/wmi.c

exit:
Maybe someone knows whether there is already a non upstream (keepalive?) patch
from QCA in their wlan-open repository (in some of the branches) which I might
miss.
Kind regards,
