Function Documentation

void td_pck_ind	(	uint8_t	vif_index,
		uint8_t	sta_index,
		bool	rx
	)

Handle reception or transmission of a packet on a given interface.

Parameters:

`[in]`	vif_index	Index of the VIF on which packet has been received/transmitted
`[in]`	sta_index	Index of the STA on which packet has been received/transmitted
`[in]`	rx	True if packet has been received, false if it has been transmitted

Referenced by rxl_frame_handle().

void td_pck_ps_ind	(	uint8_t	vif_index,
		bool	rx
	)

Handle reception or transmission of a packet on a given interface in a PS context.

This function should not be called for packet whose queue is UAPSD enabled.

Parameters:

`[in]`	vif_index	Index of the VIF on which packet has been received/transmitted
`[in]`	rx	True if packet has been received, false if it has been transmitted

void td_reset ( uint8_t vif_index )

Reset Traffic Detection status for a given VIF.

Parameters:

[in] vif_index Index of VIF on which traffic status has to be reseted

__INLINE bool td_sta_has_traffic ( uint8_t sta_idx )

Check if there is TX or RX traffic for a given STA.

Parameters:

[in] sta_index Index of STA for which the TX and RX status is checked.

Returns:: Whether the STA has TX or RX traffic

__INLINE bool td_sta_has_tx_traffic ( uint8_t sta_idx )

Check if there is TX traffic for a given STA.

Parameters:

[in] sta_index Index of STA for which the TX status is checked.

Returns:: Whether the STA has TX traffic

void td_sta_reset ( uint8_t sta_index )

Reset Traffic Detection status for a given STA.

Parameters:

[in] sta_index Index of STA on which traffic status has to be reset.

void td_start ( uint8_t vif_index )

Start Traffic Detection on a given VIF.

Parameters:

[in] vif_index Index of VIF on which traffic has to be monitored
