Add a QCA vendor sub command QCA_NL80211_VENDOR_SUBCMD_BEACON_REPORTING to implement beacon reporting feature. Different operations required to implement this feature can be specified in QCA_WLAN_VENDOR_ATTR_BEACON_REPORTING_OP_TYPE. Userspace requests the driver/firmware to periodically report received Beacon frames whose BSSID matches the current connected BSS's MAC address. If userspace requests the driver/firmware to send beacon reports actively, the driver encapsulates the details of the beacon in an event and sends it to userspace asynchronously. Otherwise, the driver will only update the beacon in cfg80211 scan cache but will not send any event to userspace. If this command is not issued, the current behavior of the driver/firmware is to update the cfg80211 scan cache only when there is a scan issued by the host in progress or whenever there is a change in IEs of the Beacon frames from the current connected BSS. The userspace requests the driver/firmware to stop reporting beacons when reporting is not required anymore. If the driver/firmware is not able to receive Beacon frames because of other Wi-Fi operations such as off-channel activities, etc., the driver/firmware sends a pause event to userspace and stops reporting Beacon frames. The driver/firmware indicates whether the beacon reporting automatically resumes later by using the QCA_WLAN_VENDOR_ATTR_BEACON_REPORTING_AUTO_RESUMES flag. If userspace doesn't want the beacon reporting to be resumed automatically, userspace can send QCA_WLAN_VENDOR_BEACON_REPORTING_OP_STOP command to the driver to stop beacon reporting.
