731  * Parameters for controlling a scan requested with
732  * IEEE80211_IOC_SCAN_REQ.
733  *
734  * Active scans cause ProbeRequest frames to be issued for each
735  * specified ssid and, by default, a broadcast ProbeRequest frame.
736  * The set of ssid's is specified in the request.
737  *
738  * By default the scan will cause a BSS to be joined (in station/adhoc
739  * mode) or a channel to be selected for operation (hostap mode).
740  * To disable that specify IEEE80211_IOC_SCAN_NOPICK and if the
741  *
742  * If the station is currently associated to an AP then a scan request
743  * will cause the station to leave the current channel and potentially
744  * miss frames from the AP.  Alternatively the station may notify the
745  * AP that it is going into power save mode before it leaves the channel.
746  * This ensures frames for the station are buffered by the AP.  This is
747  * termed a ``bg scan'' and is requested with the IEEE80211_IOC_SCAN_BGSCAN
748  * flag.  Background scans may take longer than foreground scans and may
749  * be preempted by traffic.  If a station is not associated to an AP
750  * then a request for a background scan is automatically done in the
751  * foreground.
752  *
753  * The results of the scan request are cached by the system.  This
754  * information is aged out and/or invalidated based on events like not
755  * being able to associated to an AP.  To flush the current cache
756  * contents before doing a scan the IEEE80211_IOC_SCAN_FLUSH flag may
757  * be specified.
758  *
759  * By default the scan will be done until a suitable AP is located
760  * or a channel is found for use.  A scan can also be constrained
761  * to be done once (IEEE80211_IOC_SCAN_ONCE) or to last for no more
762  * than a specified duration.

822  * There are two flavors of WDS vaps: legacy and dynamic.
823  * Legacy WDS operation implements a static binding between
824  * two stations encapsulating traffic in 4-address frames.
825  * Dynamic WDS vaps are created when a station associates to
826  * an AP and sends a 4-address frame.  If the AP vap is
827  * configured to support WDS then this will generate an
828  * event to user programs listening on the routing socket
829  * and a Dynamic WDS vap will be created to handle traffic
830  * to/from that station.  In both cases the bssid of the
831  * peer must be specified when creating the vap.
832  *
833  * By default a vap will inherit the mac address/bssid of
834  * the underlying device.  To request a unique address the
835  * IEEE80211_CLONE_BSSID flag should be supplied.  This is
836  * meaningless for WDS vaps as they share the bssid of an
837  * AP vap that must otherwise exist.  Note that some devices
838  * may not be able to support multiple addresses.
839  *
840  * Station mode vap's normally depend on the device to notice
841  * when the AP stops sending beacon frames.  If IEEE80211_CLONE_NOBEACONS
842  * is specified the net80211 layer will do this in s/w.  This
843  * is mostly useful when setting up a WDS repeater/extender where
844  * an AP vap is combined with a sta vap and the device isn't able
845  * to track beacon frames in hardware.
