Setting up Qemu with a tap interface

There are two parts to networking within QEMU:

The virtual network device that is provided to the guest (e.g. a PCI network card).
The network backend that interacts with the emulated NIC (e.g. puts packets onto the host's network).

This was tested on:

	#include <pthread.h>
	#include <stdio.h>
	#include <stdlib.h>
	#include <unistd.h>

	#define BUF_SIZE 5

	// the buffer works like a stack for
	// the sake of simplicity, if needed
	// we may implement a queue
