Name	Type	Description
ExtEthernetTapDevice	simple 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 the real TAP device on `lowerLayerOut` gate.
