Add EncapsulationMode attribute to EmuNetDevice

A student is trying to use EmuNetDevice to allow an external host to ping an NS-3 simulated node.  ARP requests are received by NS-3, then NS-3 sends an ARP reply, but the host (ubuntu) does not interpret the ARP reply.  If the host is a Windows host, then it works, Windows does receive the ARP reply.

The student is still running tests to confirm this, but we suspect that the LLC/SNAP header is what is confusing the ubuntu kernel, so I have prepared a patch to make DIX encap. possible in EmuNetDevice.

The student tells me the patch solved the problem, so it is confirmed.
