I think it's good to have but does it really fix the link monitoring issue?
Is the connection loss detected in this scenario:
- Connect to AP
- Force active mode (iw wlan0 set power_save off)
- Wait for no data activity
- HW shutdown the AP (AP leave)

Do you get any indication?

In this scenario, DB410C (wcn3620) does not report anything.

Loic
