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.
