void	mac_lld_start (MACDriver *macp)
	Configures and activates the MAC peripheral.
void	mac_lld_stop (MACDriver *macp)
	Deactivates the MAC peripheral.
msg_t	mac_lld_get_transmit_descriptor (MACDriver macp, MACTransmitDescriptor tdp)
	Returns a transmission descriptor.
void	mac_lld_release_transmit_descriptor (MACTransmitDescriptor *tdp)

void	mac_lld_release_receive_descriptor (MACReceiveDescriptor *rdp)
	Releases a receive descriptor.
bool	mac_lld_poll_link_status (MACDriver *macp)
	Updates and returns the link status.
size_t	mac_lld_write_transmit_descriptor (MACTransmitDescriptor tdp, uint8_t buf, size_t size)
	Writes to a transmit descriptor's stream.
size_t	mac_lld_read_receive_descriptor (MACReceiveDescriptor rdp, uint8_t buf, size_t size)
	Reads from a receive descriptor's stream.
uint8_t *	mac_lld_get_next_transmit_buffer (MACTransmitDescriptor tdp, size_t size, size_t sizep)
	Returns a pointer to the next transmit buffer in the descriptor chain.
const uint8_t *	mac_lld_get_next_receive_buffer (MACReceiveDescriptor rdp, size_t sizep)
	Returns a pointer to the next receive buffer in the descriptor chain.
