) |
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.
tx_frame | Pointer to the frame_info_t structure or to frame array to be transmitted |
csma_mode | Indicates mode of csma-ca to be performed for this frame |
perform_frame_retry | Indicates whether to retries are to be performed for this frame |
