724 * Parameters for controlling a scan requested with
725 * IEEE80211_IOC_SCAN_REQ.
726 *
727 * Active scans cause ProbeRequest frames to be issued for each
728 * specified ssid and, by default, a broadcast ProbeRequest frame.
729 * The set of ssid's is specified in the request.
730 *
731 * By default the scan will cause a BSS to be joined (in station/adhoc
732 * mode) or a channel to be selected for operation (hostap mode).
733 * To disable that specify IEEE80211_IOC_SCAN_NOPICK and if the
734 *
735 * If the station is currently associated to an AP then a scan request
736 * will cause the station to leave the current channel and potentially
737 * miss frames from the AP.  Alternatively the station may notify the
738 * AP that it is going into power save mode before it leaves the channel.
739 * This ensures frames for the station are buffered by the AP.  This is
740 * termed a ``bg scan'' and is requested with the IEEE80211_IOC_SCAN_BGSCAN
741 * flag.  Background scans may take longer than foreground scans and may
742 * be preempted by traffic.  If a station is not associated to an AP
743 * then a request for a background scan is automatically done in the
744 * foreground.
745 *
746 * The results of the scan request are cached by the system.  This
747 * information is aged out and/or invalidated based on events like not
748 * being able to associated to an AP.  To flush the current cache
749 * contents before doing a scan the IEEE80211_IOC_SCAN_FLUSH flag may
750 * be specified.
751 *
752 * By default the scan will be done until a suitable AP is located
753 * or a channel is found for use.  A scan can also be constrained
754 * to be done once (IEEE80211_IOC_SCAN_ONCE) or to last for no more
755 * than a specified duration.

813 * the clone request are fixed for the lifetime of the vap.
814 *
815 * There are two flavors of WDS vaps: legacy and dynamic.
816 * Legacy WDS operation implements a static binding between
817 * two stations encapsulating traffic in 4-address frames.
818 * Dynamic WDS vaps are created when a station associates to
819 * an AP and sends a 4-address frame.  If the AP vap is
820 * configured to support WDS then this will generate an
821 * event to user programs listening on the routing socket
822 * and a Dynamic WDS vap will be created to handle traffic
823 * to/from that station.  In both cases the bssid of the
824 * peer must be specified when creating the vap.
825 *
826 * By default a vap will inherit the mac address/bssid of
827 * the underlying device.  To request a unique address the
828 * IEEE80211_CLONE_BSSID flag should be supplied.  This is
829 * meaningless for WDS vaps as they share the bssid of an
830 * AP vap that must otherwise exist.  Note that some devices
831 * may not be able to support multiple addresses.
832 *
833 * Station mode vap's normally depend on the device to notice
834 * when the AP stops sending beacon frames.  If IEEE80211_CLONE_NOBEACONS
835 * is specified the net80211 layer will do this in s/w.  This
836 * is mostly useful when setting up a WDS repeater/extender where
837 * an AP vap is combined with a sta vap and the device isn't able
838 * to track beacon frames in hardware.
