Name	Type	Description
ExtEthernetTapDevice	simple module	This module provides a bidirectional connection to a real TAP device of the host computer which is running the simulation. It writes the packets arrived on 'lowerLayerIn' gate to the specified real TAP device, and sends out packets arrived from real TAP device on 'lowerLayerOut' gate.
