+ * just layers the AM dispatch (CC2420ActiveMessageM) on top of the
+ * underlying CC2420 radio packet (CC2420CsmaRadioC), which is
+ * inherently an AM packet (acknowledgements based on AM destination
+ * addr and group). Note that snooping may not work, due to CC2420
+ * early packet rejection if acknowledgements are enabled.
