For WW reg domain most of the 5 GHz channels are passive. When device listens to the beacon on that channel, the driver is updating its channel flag but firmware is not aware of it and firmware is not sending probes on that channels. Due to this, we are seeing connection failures when a device is trying to connect with hidden SSID AP. Register beacon hint notifier to the regulatory core so that driver get notified when there is a change in channel flags. Driver's notifier callback will send the updated flags to the firmware.
