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.
