One prime example is the "Extended PHR" bit which was previously reserved to now allow extend the PHR of 2 more octets giving bits 8-11 to be used for "Frame Length MSB" and bits 12-15 marked as "Reserved" - this in combination of the legacy PHR bits 0-6 labeled as "Frame Length LSB" now allows for a frame MTU of 2048 octets. > > The 802.15.4-2020 is available individually free of charge through the IEEE website through the IEEE Get Program. https://ieeexplore.ieee.org/document/9144691 > > Is there a way to prototype these new changes to the spec with the mac802154_hwsim driver? > mac802154_hwsim driver uses mac802154 the SoftMAC implementation. There are quite more changes necessary as the whole mac802154 stack deals with static 127 bytes MTU defines, etc. Unfortunately, it isn't just a driver change. - Alex
