 * Produces a Grid route probe packet.

 * E and I are this node's ethernet and IP addresses, respectively.
 * When the element's send_probe handler is called, pushes a
 * GRID_ROUTE_PROBE packet for the specified destination, with the
 * specified nonce.  This packet should probably be sent back through
 * the Grid input packet rocessing.
