NAME¶
struct_cfg80211_inform_bss - BSS inform data
SYNOPSIS¶
struct cfg80211_inform_bss {
struct ieee80211_channel * chan;
enum nl80211_bss_scan_width scan_width;
s32 signal;
u64 boottime_ns;
u64 parent_tsf;
u8 parent_bssid[ETH_ALEN];
u8 chains;
s8 chain_signal[IEEE80211_MAX_CHAINS];
};
MEMBERS¶
chan
channel the frame was received on
scan_width
scan width that was used
signal
signal strength value, according to the wiphy's signal
type
boottime_ns
timestamp (CLOCK_BOOTTIME) when the information was
received; should match the time when the frame was actually received by the
device (not just by the host, in case it was buffered on the device) and be
accurate to about 10ms. If the frame isn't buffered, just passing the return
value of ktime_get_boottime_ns is likely appropriate.
parent_tsf
the time at the start of reception of the first octet of
the timestamp field of the frame. The time is the TSF of the BSS specified by
parent_bssid.
parent_bssid[ETH_ALEN]
the BSS according to which parent_tsf is set. This
is set to the BSS that requested the scan in which the beacon/probe was
received.
chains
bitmask for filled values in chain_signal.
chain_signal[IEEE80211_MAX_CHAINS]
per-chain signal strength of last received BSS in
dBm.
