Functions
void	txl_frame_init_desc (struct txl_frame_desc_tag *frame, struct txl_buffer_tag *buffer, struct tx_hw_desc *hwdesc, struct txl_buffer_control *bufctrl)
	Basic initializations of an external TX frame descriptor (e.g such as a beacon descriptor when autonomous beacon transmission is used).
void	txl_frame_init (bool reset)
	Initializes the TX frame module environment.
struct txl_frame_desc_tag *	txl_frame_get (int type, int len)
	Get and initialize a TX frame descriptor.
void	txl_frame_prepare (struct txl_frame_desc_tag *frame, int type, int len)
	Prepare TX frame descriptor prior to transmission.
bool	txl_frame_push (struct txl_frame_desc_tag *frame, uint8_t ac)
	Push a TX frame descriptor.
void	txl_frame_cfm (struct txdesc *txdesc)
	Push a TX descriptor in the TX frame confirmation queue This function is called under interrupt by the TX control module once the frame has been transmitted.
void	txl_frame_release (struct txdesc *txdesc, bool postponed)
	Release a descriptor allocated for a packet that has not been sent.
void	txl_frame_evt (int dummy)
	Background event handler of the Tx frame module.
uint8_t	txl_frame_send_null_frame (uint8_t sta_idx, cfm_func_ptr cfm, void *env)
	Builds a NULL frame with RA address pointing to the STA passed as parameter.
uint8_t	txl_frame_send_qosnull_frame (uint8_t sta_idx, uint16_t qos, cfm_func_ptr cfm, void *env)
	Builds a QoS NULL frame with RA address pointing to the STA passed as parameter.
static void	txl_frame_tdls_add_security_header (struct txl_frame_desc_tag *frame, struct mac_hdr_qos *buf, struct key_info_tag *key)
	Add security header in a TDLS frame.
uint8_t	txl_frame_send_tdls_channel_switch_req_frame (struct tdls_chan_switch_req const *param, cfm_func_ptr cfm)
	Builds a TDLS Channel Switch Request frame.
uint8_t	txl_frame_send_tdls_channel_switch_rsp_frame (struct vif_info_tag *vif, uint16_t status_code, cfm_func_ptr cfm)
	Builds a TDLS Channel Switch Response frame.
uint8_t	txl_frame_send_tdls_peer_traffic_ind_frame (struct tdls_peer_traffic_ind_req const *param, cfm_func_ptr cfm)
	Builds a TDLS Peer Traffic Indication frame.
Variables
static struct txl_frame_desc_tag	txl_frame_desc [NX_TXFRAME_CNT]
	Pool of TX frame descriptors.
struct txl_frame_env_tag	txl_frame_env
	TX frame environment variables.
