struct txl_frame_desc_tag* txl_frame_get	(	int	type,
		int	len
	)			`[read]`

Get and initialize a TX frame descriptor.

This function is called by any module that needs to transmit a packet generated internally. The caller can choose whether it prefers to intialize the policy table (i.e. the transmission parameters) with pre-defined one or keep it un-initialized. In any case caller will be able to update parameters afterward.

Parameters:

[in]

type

Type of policy to use for transmission. Possible values are

[in] len Length of the packet to be transmitted (including FCS length)

Returns:: A pointer to the allocated TX frame descriptor, or NULL if no descriptors are available anymore.

void txl_frame_prepare	(	struct txl_frame_desc_tag *	frame,
		int	type,
		int	len
	)

Prepare TX frame descriptor prior to transmission.

This function is called by any module that needs to transmit a packet generated internally using a specific frame structure (i.e. not taken from common pool like txl_frame_get). The caller can choose whether it prefers to intialize the policy table (i.e. the transmission parameters) with pre-defined one or keep it un-initialized. In any case caller will be able to update parameters afterward.

Parameters:

[in] frame Frame to initialize (Must not be null).

[in]

bool txl_frame_push	(	struct txl_frame_desc_tag *	desc,

Parameters:

`[in]`	desc	Pointer to the descriptor previously returned by txl_frame_get
`[in]`	ac	Access category on which the frame shall be transmitted

Returns:: true if the frame was pushed successfully, false otherwise (i.e discarded because the PHY is not on the right channel and the destination is not a known station)
