NAME

       struct_ieee80211_vif - per-interface data

SYNOPSIS

       struct ieee80211_vif {
	 enum nl80211_iftype type;
	 struct ieee80211_bss_conf bss_conf;
	 u8 addr[ETH_ALEN];
	 bool p2p;
	 u8 cab_queue;
	 u8 hw_queue[IEEE80211_NUM_ACS];
	 struct ieee80211_chanctx_conf __rcu * chanctx_conf;
	 u32 driver_flags;
       #ifdef CONFIG_MAC80211_DEBUGFS
	 struct dentry * debugfs_dir;
       #endif
	 u8 drv_priv[0];
       };

MEMBERS

       type
	   type of this virtual interface

       bss_conf
	   BSS configuration for this interface, either our own or the BSS we're associated to

       addr[ETH_ALEN]
	   address of this interface

       p2p
	   indicates whether this AP or STA interface is a p2p interface, i.e. a GO or p2p-sta respectively

       cab_queue
	   content-after-beacon (DTIM beacon really) queue, AP mode only

       hw_queue[IEEE80211_NUM_ACS]
	   hardware queue for each AC

       chanctx_conf
	   The channel context this interface is assigned to, or NULL when it is not assigned. This pointer is RCU-protected due to the TX path
	   needing to access it; even though the netdev carrier will always be off when it is NULL there can still be races and packets could be
	   processed after it switches back to NULL.

       driver_flags
	   flags/capabilities the driver has for this interface, these need to be set (or cleared) when the interface is added or, if supported by
	   the driver, the interface type is changed at runtime, mac80211 will never touch this field

       debugfs_dir
	   debugfs dentry, can be used by drivers to create own per interface debug files. Note that it will be NULL for the virtual monitor
	   interface (if that is requested.)

       drv_priv[0]
	   data area for driver use, will always be aligned to sizeof(void *).

DESCRIPTION

       Data in this structure is continually present for driver use during the life of a virtual interface.

NAME

       struct_ieee80211_conf - configuration of the device

SYNOPSIS

       struct ieee80211_conf {
	 u32 flags;
	 int power_level;
	 int dynamic_ps_timeout;
	 int max_sleep_period;
	 u16 listen_interval;
	 u8 ps_dtim_period;
	 u8 long_frame_max_tx_count;
	 u8 short_frame_max_tx_count;
	 struct cfg80211_chan_def chandef;
	 bool radar_enabled;
	 enum ieee80211_smps_mode smps_mode;
       };

MEMBERS

       flags
	   configuration flags defined above

       power_level
	   requested transmit power (in dBm), backward compatibility value only that is set to the minimum of all interfaces

       dynamic_ps_timeout
	   The dynamic powersave timeout (in ms), see the powersave documentation below. This variable is valid only when the CONF_PS flag is set.

       max_sleep_period
	   the maximum number of beacon intervals to sleep for before checking the beacon for a TIM bit (managed mode only); this value will be
	   only achievable between DTIM frames, the hardware needs to check for the multicast traffic bit in DTIM beacons. This variable is valid
	   only when the CONF_PS flag is set.

       listen_interval
	   listen interval in units of beacon interval

       ps_dtim_period
	   The DTIM period of the AP we're connected to, for use in power saving. Power saving will not be enabled until a beacon has been
	   received and the DTIM period is known.

       long_frame_max_tx_count
	   Maximum number of transmissions for a "long" frame (a frame not RTS protected), called "dot11LongRetryLimit" in 802.11, but actually
	   means the number of transmissions not the number of retries

       short_frame_max_tx_count
	   Maximum number of transmissions for a "short" frame, called "dot11ShortRetryLimit" in 802.11, but actually means the number of
	   transmissions not the number of retries

       chandef
	   the channel definition to tune to

       radar_enabled
	   whether radar detection is enabled

       smps_mode
	   spatial multiplexing powersave mode; note that IEEE80211_SMPS_STATIC is used when the device is not configured for an HT channel. Note
	   that this is only valid if channel contexts are not used, otherwise each channel context has the number of chains listed.

DESCRIPTION

       This struct indicates how the driver shall configure the hardware.
