// Module interface for modules providing Ethernet switch functionality.
// These modules handle the mapping between ports and MAC addresses,
// and forward frames to appropriate ports.
//
// Functions:
// - relays frames based on their dest MAC addresses (dest-->port mapping)
// - models finite buffer size (drops) and finite processing power (latency, queueing)
//
// Address caching is modeled by a fixed-size lookup table.
// When the table is full, the oldest address is kicked out of the cache.
//
// Entries are also deleted if their age exceeds a certain limit.
//
// If needed, address tables can be pre-loaded from text files at the beginning
// of the simulation; this controlled by the forwardingTableFile module parameter.
//
// This module is not a concrete implementation, it just defines gates and
// parameters a ~IMacRelayUnit should have. Concrete inplementations add
// capacity and performance aspects to the model (number of frames processed
// per second, amount of memory available in the switch, etc.)
//
// Known implementations are ~MacRelayUnit and ~Ieee8021dRelay.
