STRUCT 
IEEE80211_HW(9)					  The basic mac80211 driver inte				    STRUCT IEEE80211_HW(9)

NAME

       struct_ieee80211_hw - hardware information and state

SYNOPSIS

       struct ieee80211_hw {
	 struct ieee80211_conf conf;
	 struct wiphy * wiphy;
	 const char * rate_control_algorithm;
	 void * priv;
	 u32 flags;
	 unsigned int extra_tx_headroom;
	 int channel_change_time;
	 int vif_data_size;
	 int sta_data_size;
	 u16 queues;
	 u16 max_listen_interval;
	 s8 max_signal;
	 u8 max_rates;
	 u8 max_rate_tries;
       };

MEMBERS

       conf

	   struct ieee80211_conf, device configuration, don't use.

       wiphy
	   This points to the struct wiphy allocated for this 802.11 PHY. You must fill in the perm_addr and dev members of this structure using
	   SET_IEEE80211_DEV and SET_IEEE80211_PERM_ADDR. Additionally, all supported bands (with channels, bitrates) are registered here.

       rate_control_algorithm
	   rate control algorithm for this hardware. If unset (NULL), the default algorithm will be used. Must be set before calling
	   ieee80211_register_hw.

       priv
	   pointer to private area that was allocated for driver use along with this structure.

       flags
	   hardware flags, see enum ieee80211_hw_flags.

       extra_tx_headroom
	   headroom to reserve in each transmit skb for use by the driver (e.g. for transmit headers.)

       channel_change_time
	   time (in microseconds) it takes to change channels.

       vif_data_size
	   size (in bytes) of the drv_priv data area within struct ieee80211_vif.

       sta_data_size
	   size (in bytes) of the drv_priv data area within struct ieee80211_sta.

       queues
	   number of available hardware transmit queues for data packets. WMM/QoS requires at least four, these queues need to have configurable
	   access parameters.

       max_listen_interval
	   max listen interval in units of beacon interval that HW supports

       max_signal
	   Maximum value for signal (rssi) in RX information, used only when IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB

       max_rates
	   maximum number of alternate rate retry stages

       max_rate_tries
	   maximum number of tries for each stage

DESCRIPTION

       This structure contains the configuration and hardware information for an 802.11 PHY.

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.
