/**
 * Original TinyOS T-Frames use a packet header that is not compatible with
 * other 6LowPAN networks.  They do not include the network byte 
 * responsible for identifying the packing as being sourced from a TinyOS
 * network.
 *
 * TinyOS I-Frames are interoperability packets that do include a network
 * byte as defined by 6LowPAN specifications.  The I-Frame header type is
 * the default packet header used in TinyOS networks.
 *
 * Since either packet header is acceptable, this layer must do some 
 * preprocessing (sorry) to figure out whether or not it needs to include 
 * the functionality to process I-frames.  If I-Frames are used, then
 * the network byte is added on the way out and checked on the way in.
 * If the packet came from a network different from a TinyOS network, the
 * user may access it through the DispatchP's NonTinyosReceive[] Receive 
 * interface and process it in a different radio stack.
 *
 * If T-Frames are used instead, this layer is simply pass-through wiring to the
 * layer beneath.  
 *
 * Define "CC2420_IFRAME_TYPE" to use the interoperability frame and 
 * this layer
