32 * @id: Unique identifier for this BSS entry
33 * @scan_miss_count: Number of counts without seeing this BSS
34 * @flags: information flags about the BSS/IBSS (WPA_BSS_*)
35 * @last_update_idx: Index of the last scan update
37 * @freq: frequency of the channel in MHz (e.g., 2412 = channel 1)
38 * @beacon_int: beacon interval in TUs (host byte order)
39 * @caps: capability information field in host byte order
40 * @qual: signal quality
42 * @level: signal level
43 * @tsf: Timestamp of last Beacon/Probe Response frame
44 * @last_update: Time of the last update (i.e., Beacon or Probe Response RX)
45 * @ie_len: length of the following IE field in octets (from Probe Response)
46 * @beacon_ie_len: length of the following Beacon IE field in octets
48 * This structure is used to store information about neighboring BSSes in
49 * generic format. It is mainly updated based on scan results from the driver.
