MEMBERS¶
channel
channel this BSS is on
scan_width
width of the control channel
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.
transmitted_bss
pointer to the transmitted BSS, if this is a
non-transmitted one (multi-BSSID support)
nontrans_list
list of non-transmitted BSS, if this is a transmitted one
(multi-BSSID support)
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
chains
bitmask for filled values in chain_signal.
chain_signal[IEEE80211_MAX_CHAINS]
per-chain signal strength of last received BSS in
dBm.
bssid_index
index in the multiple BSS set
max_bssid_indicator
max number of members in the BSS set
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.
