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.

       };

MEMBERS

       wiphy
	   pointer to hardware description

       iftype
	   interface type

       list
	   (private) Used to collect the interfaces

       netdev
	   (private) Used to reference back to the netdev, may be NULL

       identifier
	   (private) Identifier used in nl80211 to identify this wireless device if it has no netdev

       mgmt_registrations
	   list of registrations for management frames

       mgmt_registrations_lock
	   lock for the list

       mtx
	   mutex used to lock data in this struct

       cleanup_work
	   work struct used for cleanup that can't be done directly

       use_4addr
	   indicates 4addr mode is used on this interface, must be set by driver (if supported) on add_interface BEFORE registering the netdev and
	   may otherwise be used by driver read-only, will be update by cfg80211 on change_interface

       p2p_started
	   true if this is a P2P Device that has been started

       address[ETH_ALEN]
	   The address for this device, valid only if netdev is NULL

       ssid[IEEE80211_MAX_SSID_LEN]
	   (private) Used by the internal configuration code

       ssid_len
	   (private) Used by the internal configuration code

       mesh_id_len
	   (private) Used by the internal configuration code

       mesh_id_up_len
	   (private) Used by the internal configuration code

       wext
	   (private) Used by the internal wireless extensions compat code

DESCRIPTION

       For netdevs, this structure must be allocated by the driver that uses the ieee80211_ptr field in struct net_device (this is intentional so
       it can be allocated along with the netdev.) It need not be registered then as netdev registration will be intercepted by cfg80211 to see
       the new wireless device.

       For non-netdev uses, it must also be allocated by the driver in response to the cfg80211 callbacks that require it, as there's no netdev
       registration in that case it may not be allocated outside of callback operations that return it.
