retval_t tal_tx_frame ( frame_info_t tx_frame,
csma_mode_t  csma_mode,
bool  perform_frame_retry 
)

Requests to TAL to transmit frame.

This function is called by the MAC to deliver a frame to the TAL to be transmitted by the transceiver.

Parameters
tx_framePointer to the frame_info_t structure or to frame array to be transmitted
csma_modeIndicates mode of csma-ca to be performed for this frame
perform_frame_retryIndicates whether to retries are to be performed for this frame
Returns
MAC_SUCCESS if the TAL has accepted the data from the MAC for frame transmission TAL_BUSY if the TAL is busy servicing the previous MAC request
