Detailed Description

IEEE 802.15.4 MAC information element (IE) related types and helpers.

This is not to be included by the application. This file contains only those parts of the types required for IE support that need to be visible to IEEE 802.15.4 drivers and L2 at the same time, i.e. everything related to header IE representation, parsing and generation.

All specification references in this file refer to IEEE 802.15.4-2020.

Note
All structs and attributes in this file that directly represent parts of IEEE 802.15.4 frames are in LITTLE ENDIAN, see section 4, especially section 4.3.
