[nexus] add test 6.4.1 Link-Local Addressing (#12483)
This commit adds a new Nexus test case for 'Link-Local Addressing'
(6.4.1) as specified in the test specification.
Summary of changes:
- Implemented Nexus test 6.4.1:
- Added tests/nexus/test_6_4_1.cpp: Implements the test execution
for both Topology A (End Device 'ED_1') and Topology B (Sleepy End
Device 'SED_1'). The test verifies unicast and multicast ICMPv6 Echo
Request/Reply using Link-Local addresses. Fragmented and
non-fragmented packets are tested. The test uses direct method
calls, sets log level to note, and uses AllowList for
connectivity.
- Added tests/nexus/verify_6_4_1.py: PCAP verification script.
Validates the exchange of ICMPv6 Echo packets for unicast
(Extended Address-based LLA) and multicast (All Thread Nodes and
All Nodes) addresses.
- Updated build and execution scripts:
- Modified tests/nexus/CMakeLists.txt to build the new test.
- Updated tests/nexus/run_nexus_tests.sh to include 6_4_1 in the
default test list and added expansion logic for A/B topologies.
