Scapy IEEE 802.15.4 processing is based on version 2011?

Brief description

Comparing a Scapy application's parsing of a known good 802.15.4 PCAPNG (with latest Wireshark). Hex packet dumps match, so the frame boundaries are correct. Scapy is not correctly parsing (at least) the source addresses, destination addresses, PAN IDs, etc. from the frames.

Scapy appears to be coded to IEEE 802.15.4-2011? The capture adheres to IEEE 802.15.4-2020 (note fcf_framever= 2), whose frame control has new fields controlling sequence number suppression, Information Element presence, and new PAN ID suppression logic since 2011.

Scapy version

2.7.0

Python version

3.14.3

Operating system

Windows 11

How to reproduce

Scapy output... note PAN ID compression in the frame control field is set to True, yet a PAN ID is parsed which seems to also corrupt at least the source and destination address parsing.

Start with Scapy 2.7.0's IEEE 802.15.4 parsing and compare it against the supplied frame bytes and Wireshark output. Investigate frame version 2, PAN ID compression, sequence-number suppression, Information Element presence, and address fields; done means the destination and source addresses and PAN IDs are parsed correctly for the supplied 802.15.4-2020 capture.
