MEMBERS

19       chan
20           channel the frame was received on
21
22       scan_width
23           scan width that was used
24
25       signal
26           signal strength value, according to the wiphy's signal type
27
28       boottime_ns
29           timestamp (CLOCK_BOOTTIME) when the information was received;
30           should match the time when the frame was actually received by the
31           device (not just by the host, in case it was buffered on the
32           device) and be accurate to about 10ms. If the frame isn't buffered,
33           just passing the return value of ktime_get_boot_ns is likely
34           appropriate.
35
36       parent_tsf
37           the time at the start of reception of the first octet of the
38           timestamp field of the frame. The time is the TSF of the BSS
39           specified by parent_bssid.
40
41       parent_bssid[ETH_ALEN]
42           the BSS according to which parent_tsf is set. This is set to the
43           BSS that requested the scan in which the beacon/probe was received.
