Functions
uint8_t	mac_createSicslowpanLongAddr (uint8_t *ethernet, uip_lladdr_t *lowpan)
	Create a 802.15.4 long address from a 802.3 address.
uint8_t	mac_createEthernetAddr (uint8_t *ethernet, uip_lladdr_t *lowpan)
	Create a 802.3 address from a 802.15.4 long address.
uint8_t	mac_createDefaultEthernetAddr (uint8_t *ethernet)
	Create a 802.3 address (default)
void	mac_ethhijack (const struct mac_driver *r)

void	mac_ethernetToLowpan (uint8_t *ethHeader)
	Take a packet received over the ethernet link, and send it out over 802.15.4.
void	mac_LowpanToEthernet (void)

Variables
uint64_t	macLongAddr
	Our own long address.
struct mac_driver *	pmac

Function Documentation

void mac_802154raw

(

const struct mac_driver *

r

)

Process a received 6lowpan packet.

Parameters:

r	The MAC layer

The 6lowpan packet is put in packetbuf by the MAC. This routine passes it directly to the ethernet layer without decompressing.

void mac_logTXtoEthernet	(	frame_create_params_t *	p,
		frame_result_t *	frame_result
	)

Logs a sent 6lowpan frame.

This routine passes a frame directly to the ethernet layer without decompressing.
