This commit enables channel-based filtering in Nexus simulation tests
by exporting node channel information and enhancing the pktverify
library to extract and use it.
Simulation Core:
- Export each node's PAN channel to the test JSON metadata in
nexus_core.cpp.
Pktverify Library:
- Update packet.py to extract channel information from 'wpan-tap' or
'wpan_tap' layers and normalize it into 'wpan.channel'.
- Update consts.py and layer_fields.py to support the new TAP layers
and their channel fields.
- Enhance NullField to be callable and iterable, and update Bytes
comparison to handle NullField, preventing script crashes when
accessing missing layers or fields.
Verification Utilities:
- Automatically load channel information from test JSON into
verification variables (e.g., {NODE_NAME}_CHANNEL).
Test Updates:
- Stabilize 1.1.9.2.14 by using channel-based filtering instead of
relying solely on RLOC16s.
- Update 1.1.9.2.17 and 1.1.9.2.8 to use the normalized
'wpan.channel' field instead of direct 'wpan_tap' access.
