  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.

  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.
