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
flags: bit field of flags controlling operation
rates[IEEE80211_NUM_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
wiphy: the wiphy this was for
scan_start: time (in jiffies) when the scan started
aborted: (internal) scan request was notified as aborted
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.
