Dummy encapsulation/decapsulation module for EthernetInterface.

Expected environment:

• lowerLayerIn, lowerLayerOut gates should be connected to an EtherMAC
• upperLayerIn, upperLayerOut gates should be connected to an IMACRelayUnit

Functionality:

• packets coming from upper layers will be sent to MAC.
• Ethernet frames arriving from MAC will be sent up to the higher layers.
