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

 * Virtual AP cloning parameters.  The parent device must

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