@bingwang-ms PR conflicts with 202411 branch

[rbpittman]

@bingwang-ms Can confirm saw a test failure against 202411 for PCBB tests saying Fixture "disable_packet_aging" called directly.
Edit: This is only because of an excess change I had in #17889 that I have now removed.

Hi @bingwang-ms , this PR leads to test_xoff_for_pcbb failure due to:

python: can't open file '/packets_aging.py': [Errno 2] No such file or directory

the packets_aging.py had been removed by fixture update_docker_services.

Hi @bingwang-ms , any update?
