Name	Type	Description
MacRelayUnitBase	simple module	Abstract base module for MAC relay unit implementations (Ethernet switches). Provides core functionality for MAC address learning and frame forwarding in bridged Ethernet networks. Contains functionality for maintaining a MAC address table that maps addresses to ports, learning addresses from incoming frames, and forwarding frames to appropriate interfaces. It is able to handle unicast, multicast, and broadcast traffic according to standard Ethernet switching rules.
