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.
