[nexus] add test 7.1.1 Network Data Propagation (#12492)
This commit adds a new Nexus test case for 'Network data propagation'
(7.1.1) as specified in the Thread Test Specification.
The test verifies that the DUT, acting as a Border Router and Leader,
correctly sets Network Data (stable and non-stable) and successfully
propagates it to various child types (Router, MED, and SED) during the
attach and child update processes.
Summary of changes:
- tests/nexus/test_7_1_1.cpp: Implements the test logic.
- Configures a network with a Leader (DUT), Router_1, MED_1, and
SED_1.
- Sets up On-Mesh Prefixes on the Leader (one stable, one non-stable)
and registers them.
- Sequentially attaches Router_1, SED_1, and MED_1.
- Advances time to allow for MLE Child ID and Child Update
exchanges.
- Uses direct core method calls and sets log level to note.
- tests/nexus/verify_7_1_1.py: Python PCAP verification script.
- Verifies MLE Advertisements from the Leader.
- Validates MLE Child ID Responses to Router_1 and MED_1 contain
both prefixes.
- Validates MLE Child ID Response to SED_1 contains only the stable
prefix and ensures P_border_router_16 is 0xFFFE.
- Verifies the Child Update exchange with required TLVs for MED_1
and SED_1.
- tests/nexus/CMakeLists.txt: Added the new test to the build system.
- tests/nexus/run_nexus_tests.sh: Added 7_1_1 to the default test list.
