Hi Elaine,

If you look at gnuradio-examples/python/gmsk/tunnel_ip_null_mac,
you'll see how to pass packets to and from the networking layer using
the "tun" interface.

In benchmark_gmsk_rx, look for the function rx_callback.  It's called
with the received data in the "payload" argument as a python string.
