+ * NOTE: These structures are used as convenient facade for accessing
+ * the encapsulated headers. They are not written taking compiler padding
+ * into account, then a sizeof() on these struct could not give the expected
+ * result. For accessing the size of the hicn headers use the macros at the end of
