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

  826  * There are two flavors of WDS vaps: legacy and dynamic.

  832  * event to user programs listening on the routing socket
  833  * and a Dynamic WDS vap will be created to handle traffic
  834  * to/from that station.  In both cases the bssid of the
  835  * peer must be specified when creating the vap.
  836  *
  837  * By default a vap will inherit the mac address/bssid of
  838  * the underlying device.  To request a unique address the
  839  * IEEE80211_CLONE_BSSID flag should be supplied.  This is
  840  * meaningless for WDS vaps as they share the bssid of an
  841  * AP vap that must otherwise exist.  Note that some devices
  842  * may not be able to support multiple addresses.
  843  *
  844  * Station mode vap's normally depend on the device to notice
  845  * when the AP stops sending beacon frames.  If IEEE80211_CLONE_NOBEACONS
  846  * is specified the net80211 layer will do this in s/w.  This
  847  * is mostly useful when setting up a WDS repeater/extender where
  848  * an AP vap is combined with a sta vap and the device isn't able
  849  * to track beacon frames in hardware.
