CFG80211_INFORM_BSS(9) Scanning and BSS list handling CFG80211_INFORM_BSS(9)NAME
cfg80211_inform_bss - inform cfg80211 of a new BSS
SYNOPSIS
struct cfg80211_bss * cfg80211_inform_bss(struct wiphy * wiphy, struct ieee80211_channel * channel, const u8 * bssid, u64 tsf,
u16 capability, u16 beacon_interval, const u8 * ie, size_t ielen, s32 signal, gfp_t gfp);
ARGUMENTS
wiphy
the wiphy reporting the BSS
channel
The channel the frame was received on
bssid
the BSSID of the BSS
tsf
the TSF sent by the peer in the beacon/probe response (or 0)
capability
the capability field sent by the peer
beacon_interval
the beacon interval announced by the peer
ie
additional IEs sent by the peer
ielen
length of the additional IEs
signal
the signal strength, type depends on the wiphy's signal_type
gfp
context flags
DESCRIPTION
This informs cfg80211 that BSS information was found and the BSS should be updated/added.
RETURN
A referenced struct, must be released with cfg80211_put_bss! Or NULL on error.

struct_cfg80211_bss - BSS description
SYNOPSIS
struct cfg80211_bss {
struct ieee80211_channel * channel;
const struct cfg80211_bss_ies __rcu * ies;
const struct cfg80211_bss_ies __rcu * beacon_ies;

struct cfg80211_bss * hidden_beacon_bss;
s32 signal;
u16 beacon_interval;
u16 capability;
u8 bssid[ETH_ALEN];
u8 priv[0];
};
MEMBERS
channel
channel this BSS is on
ies
the information elements (Note that there is no guarantee that these are well-formed!); this is a pointer to either the beacon_ies or
proberesp_ies depending on whether Probe Response frame has been received. It is always non-NULL.
beacon_ies
the information elements from the last Beacon frame (implementation note: if hidden_beacon_bss is set this struct doesn't own the
beacon_ies, but they're just pointers to the ones from the hidden_beacon_bss struct)
proberesp_ies
the information elements from the last Probe Response frame
hidden_beacon_bss
in case this BSS struct represents a probe response from a BSS that hides the SSID in its beacon, this points to the BSS struct that
holds the beacon data. beacon_ies is still valid, of course, and points to the same data as hidden_beacon_bss->beacon_ies in that
case.
signal
signal strength value (type depends on the wiphy's signal_type)
beacon_interval
the beacon interval as from the frame
capability
the capability field in host byte order
bssid[ETH_ALEN]
BSSID of the BSS
priv[0]
private area for driver use, has at least wiphy->bss_priv_size bytes
DESCRIPTION
This structure describes a BSS (which may also be a mesh network) for use in scan results and similar.
