Function Documentation

void mac_802154raw ( const struct mac_driver r)

Process a received 6lowpan packet.

Parameters
rThe MAC layer

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

Definition at line 1118 of file sicslow_ethernet.c.

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.
