Functions
void	macInit (void)
	MAC Driver initialization.
void	macObjectInit (MACDriver *macp)
	Initialize the standard part of a MACDriver structure.
void	macStart (MACDriver *macp, const MACConfig *config)
	Configures and activates the MAC peripheral.
void	macStop (MACDriver *macp)
	Deactivates the MAC peripheral.
msg_t	macWaitTransmitDescriptor (MACDriver *macp, MACTransmitDescriptor *tdp, systime_t time)
	Allocates a transmission descriptor.
void	macReleaseTransmitDescriptor (MACTransmitDescriptor *tdp)
	Releases a transmit descriptor and starts the transmission of the enqueued data as a single frame.
msg_t	macWaitReceiveDescriptor (MACDriver *macp, MACReceiveDescriptor *rdp, systime_t time)
	Waits for a received frame.
void	macReleaseReceiveDescriptor (MACReceiveDescriptor *rdp)
	Releases a receive descriptor.
bool_t	macPollLinkStatus (MACDriver *macp)
	Updates and returns the link status.

Macro Functions
#define	macGetReceiveEventSource(macp)   (&(macp)->rdevent)
	Returns the received frames event source.
#define	macWriteTransmitDescriptor(tdp, buf, size)   mac_lld_write_transmit_descriptor(tdp, buf, size)
	Writes to a transmit descriptor's stream.
#define	macReadReceiveDescriptor(rdp, buf, size)   mac_lld_read_receive_descriptor(rdp, buf, size)
	Reads from a receive descriptor's stream.
#define	macGetNextTransmitBuffer(tdp, size, sizep)   mac_lld_get_next_transmit_buffer(tdp, size, sizep)
	Returns a pointer to the next transmit buffer in the descriptor chain.
#define	macGetNextReceiveBuffer(rdp, sizep)   mac_lld_get_next_receive_buffer(rdp, sizep)
	Returns a pointer to the next receive buffer in the descriptor chain.
Typedefs
typedef struct MACDriver	MACDriver
	Type of a structure representing a MAC driver.
Enumerations
enum	macstate_t { MAC_UNINIT = 0, MAC_STOP = 1, MAC_ACTIVE = 2 }
	Driver state machine possible states. More...
