Functions
int	macif_init (void)
	Initialize the MAC interface.
void	macif_msg_evt (int dummy)
	Kernel event handler for the handling of messages pushed by control layer.
void	macif_kmsg_fwd (const struct ke_msg *ke_msg)
	Forward a kernel message to the MAC interface.
void	macif_prim_tbtt_ind (void)
	Indicate control layer that the primary TBTT is pending.
void	macif_sec_tbtt_ind (void)
	Indicate control layer that the secondary TBTT is pending.
uint8_t	macif_rx_get_packet_threshold (void)
	Get the number of received packets above which the host shall be warned.
void	macif_rx_data_ind (void)
	Signal to the upper layers the presence of data in the host RX buffers.
bool	macif_rx_buf_check (void)
	Checks if a host buffer is currently available.
uint32_t	macif_rx_buf_get (uint32_t *host_id)
	Retrieve a RX host buffer address for future DMA transfer.
void	macif_rx_desc_upload (struct co_list *desc_list)

static bool	macif_tx_cfm_lli_done (uint16_t next_lli_cnt)
	This function checks if the IPC DMA already processed the transfers up to the target count.
void	macif_tx_cfm_start (uint8_t access_category)
	Initialize a new TX confirmation upload process.
void	macif_tx_cfm_push (uint8_t access_category, struct txdesc *txdesc)
	Push a TX confirmation for upload to upper layers.
void	macif_tx_cfm_done (uint8_t access_category, bool poll)

void	macif_tx_cfm_dma_int_handler (void)
	Handler for DMA transfer of confirmations.
Variables
struct macif_ipc_env_tag	macif_ipc_env
	MACIF IPC context.
