MEMBERS

       ssids
	   SSIDs to scan for (active scan only)

       n_ssids
	   number of SSIDs

       n_channels
	   total number of channels to scan

       ie
	   optional information element(s) to add into Probe Request or NULL

       ie_len
	   length of ie in octets

       flags
	   bit field of flags controlling operation

       rates[IEEE80211_NUM_BANDS]
	   bitmap of rates to advertise for each band

       wdev
	   the wireless device to scan for

       wiphy
	   the wiphy this was for

       scan_start
	   time (in jiffies) when the scan started

       aborted
	   (internal) scan request was notified as aborted

       no_cck
	   used to send probe requests at non CCK rate in 2GHz band

       channels[0]
	   channels to scan on.

STRUCT 
CFG80211_BSS(9)					  Scanning and BSS list handling				    STRUCT CFG80211_BSS(9)

NAME

       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;
	 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

       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.
