-/* The IEEE 802.15.4 standard defines 4 MAC packet types:
- * - beacon frame
- * - MAC command frame
- * - acknowledgement frame
- * - data frame

- * and only the data frame should be pushed to the upper layers, other types
- * are just internal MAC layer management information. So only data packets
