IEEE80211_ALLOC_HW(9)					  The basic mac80211 driver inte				     IEEE80211_ALLOC_HW(9)

NAME

       ieee80211_alloc_hw - Allocate a new hardware device

SYNOPSIS

       struct ieee80211_hw * ieee80211_alloc_hw(size_t priv_data_len, const struct ieee80211_ops * ops);

ARGUMENTS

       priv_data_len
	   length of private data

       ops
	   callbacks for this device

DESCRIPTION

       This must be called once for each hardware device. The returned pointer must be used to refer to this device when calling other functions.
       mac80211 allocates a private data area for the driver pointed to by priv in struct ieee80211_hw, the size of this area is given as
       priv_data_len.

RETURN

       A pointer to the new hardware device, or NULL on error.

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.
