+/**
+ * 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
