ieee80211_tx_info_clear_status(9) [centos man page]

IEEE80211_TX_INFO_CL(9) 				  The basic mac80211 driver inte				   IEEE80211_TX_INFO_CL(9)

NAME

       ieee80211_tx_info_clear_status - clear TX status

SYNOPSIS

       void ieee80211_tx_info_clear_status(struct ieee80211_tx_info * info);

ARGUMENTS

       info
	   The struct ieee80211_tx_info to be cleared.

DESCRIPTION

       When the driver passes an skb back to mac80211, it must report a number of things in TX status. This function clears everything in the TX
       status but the rate control information (it does clear the count since you need to fill that in anyway).

NOTE

       You can only use this function if you do NOT use info->driver_data! Use info->rate_driver_data instead if you need only the less space that
       allows.

SYNOPSIS

       struct ieee80211_vif {

	 struct ieee80211_bss_conf bss_conf;
	 u8 addr[ETH_ALEN];

       };

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.
