Commit Message

Petr Machata June 16, 2025, 10:44 p.m. UTC 
Add tests for MC-routing underlay VXLAN traffic.

Signed-off-by: Petr Machata <petrm@nvidia.com>

Notes:
    v3:
    - Disable shellchecking apparently-unreachable commands.
      They are actually reachable through tests_run, in_ns, etc.
    - Run setup_wait with an explicit argument to avoid
      shellcheck citation.
    
    v2:
    - Adjust as per shellcheck citations
