MEMBERS

channel
channel this BSS is on
bssid[ETH_ALEN]
BSSID of the BSS
tsf
timestamp of last received update
beacon_interval
the beacon interval as from the frame
capability
the capability field in host byte order
information_elements
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
len_information_elements
total length of the information elements
beacon_ies
the information elements from the last Beacon frame
len_beacon_ies
total length of the beacon_ies
proberesp_ies
the information elements from the last Probe Response frame
len_proberesp_ies
total length of the proberesp_ies
signal
signal strength value (type depends on the wiphy's signal_type)
free_priv
function pointer to free private data
priv[0] __attribute__((__aligned__(sizeof(void *))))
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.
