wcn36xx: connection monitoring issue

[Damien Riegel]

Hi,


I'm working on a board derived from the DragonBoard-410c (apq8016 +
wcn3620) and noticed an issue with WiFi connection monitoring. When I
get out of the range of the access point, the device stays associated,
no matter how far I go or how long I wait.

The chip on this board is the WCN3620, and the driver sets
IEEE80211_HW_CONNECTION_MONITOR at drivers/net/wireless/ath/wcn36xx/main.c:1127, 
so the hardware is supposed to do the monitoring, but it looks like it
doesn't. If I comment out this flag (snippet at the end of the email),
the correct behaviour is observed.

Has anyone else noticed that issue?


Thanks,
Damien
