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:
[130462.603539] rtw_8821ce 0000:02:00.0: stop vif ee:a4:95:4e:53:8b on port 0
[130463.116843] rtw_8821ce 0000:02:00.0: start vif aa:fc:19:66:5e:e2 on port 0
[130874.613430] rtw_8821ce 0000:02:00.0: stop vif aa:fc:19:66:5e:e2 on port 0
[130875.122641] rtw_8821ce 0000:02:00.0: start vif d2:e6:23:ba:98:76 on port 0
[131286.677828] rtw_8821ce 0000:02:00.0: stop vif d2:e6:23:ba:98:76 on port 0
[131287.192108] rtw_8821ce 0000:02:00.0: start vif 82:c4:33:96:2e:c6 on port 0\
After ~411 secs, the callback routine for remove_interface() in struct
ieee80211_ops is called. After <1 sec, the add_interface() callback is called to
restart the vif. Is this normal behavior and I see it in the logs because this
driver is the only one that logs the start/stop calls, or is something else
going on? It would be easy to disable those log entries, but I would like to
know if there is some other condition?
On my kernel, HZ is 250, thus the interval is roughly 103,000 jiffies.
Thanks,
Larry
