Detailed Description

The MAC or data link layer provides basic functions to access the underlaying physical layer.

This physical layer and parts of the MAC layer are part of the ethernet transceiver. Additional functions like hardware initialisization, packet transmission and receiption must be done in software. The functions of this group do this job.
