+ * @flags: information flags about the BSS/IBSS (WPA_BSS_*)
+ * @last_update_idx: Index of the last scan update
+ * @bssid: BSSID
+ * @freq: frequency of the channel in MHz (e.g., 2412 = channel 1)
+ * @beacon_int: beacon interval in TUs (host byte order)
+ * @caps: capability information field in host byte order
+ * @qual: signal quality
+ * @noise: noise level
+ * @level: signal level
+ * @tsf: Timestamp of last Beacon/Probe Response frame
+ * @last_update: Time of the last update (i.e., Beacon or Probe Response RX)
