MEMBERS
       ssids
           SSIDs to scan for (active scan only)

       n_ssids
           number of SSIDs

       n_channels
           total number of channels to scan

       scan_width
           channel width for scanning

       ie
           optional information element(s) to add into Probe Request or NULL

       ie_len
           length of ie in octets

       duration
           how long to listen on each channel, in TUs. If duration_mandatory is not set, this is
           the maximum dwell time and the actual dwell time may be shorter.

       duration_mandatory
           if set, the scan duration must be as specified by the duration field.

       flags
           bit field of flags controlling operation

       rates[NUM_NL80211_BANDS]
           bitmap of rates to advertise for each band

       wdev
           the wireless device to scan for

       mac_addr[ETH_ALEN]
           MAC address used with randomisation

       mac_addr_mask[ETH_ALEN]
           MAC address mask used with randomisation, bits that are 0 in the mask should be
           randomised, bits that are 1 should be taken from the mac_addr

       bssid[ETH_ALEN]
           BSSID to scan for (most commonly, the wildcard BSSID)

       wiphy
           the wiphy this was for

       scan_start
           time (in jiffies) when the scan started

       info
           (internal) information about completed scan

       notified
           (internal) scan request was notified as done or aborted

       no_cck
           used to send probe requests at non CCK rate in 2GHz band

       channels[0]
           channels to scan on.
