Ping-Ke and list,
Within the last couple of days, I was testing rtw88 with an rtl8821ce card. I
noticed that whenever the device is not connected to an AP, the log is flooded
with messages like the following:

I turn off UI network-manager, and it can show the same messages if I use
'ifconfig' to up and down the interfaces. I think add_interface()/remove_interface()
are called by ieee80211_do_open()/ieee80211_do_stop() in my test cases.
Please check if your network-manager does the things. If so, check syslog to
know why it does.
Utility journalctl show the following for a couple of cycles from start- to
stop-vif:

From these log entries, I see no reason why there should be a stop-vif 412
seconds after the interface is set from disabled to disconnected. This cycling
does not cause any problems. Perhaps the statements that do the logging should
be removed.
