Ethernet Layer 2 MAC Overview

The layer 2 MAC component implements a layer 2 ethernet MAC. It provides both MII communication to the PHY and MAC transport layer for ethernet packets and enables several clients to connect to it and send and receive packets.

Two independent implementations are available. The FULL implementation runs on 5 logical cores, allows multiple clients with independent buffering per client and supports accurate packet timestamping, priority queuing, and 802.1Qav traffic shaping. The LITE implementation runs on two logical cores but is restricted to a single receive and trasnmit client and does not support any advanced features.
