STRUCT CFG80211_BSS(9) | Scanning and BSS list handling | STRUCT CFG80211_BSS(9) |
NAME¶
struct_cfg80211_bss - BSS descriptionSYNOPSIS¶
struct cfg80211_bss { struct ieee80211_channel * channel; enum nl80211_bss_scan_width scan_width; const struct cfg80211_bss_ies __rcu * ies; const struct cfg80211_bss_ies __rcu * beacon_ies; const struct cfg80211_bss_ies __rcu * proberesp_ies; struct cfg80211_bss * hidden_beacon_bss; s32 signal; u16 beacon_interval; u16 capability; u8 bssid[ETH_ALEN]; u8 priv[0]; };
MEMBERS¶
channelchannel 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.
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.AUTHOR¶
