Approach

What is the motivation for this PR?

We had added the fixture to disable the voqWD.

sonic-mgmt/tests/snappi_tests/pfcwd/test_pfcwd_actions.py

Line 18 in 939485f

from tests.snappi_tests.cisco.helper import disable_voq_watchdog # noqa: F401

But every tests does config reload on the DUT’s which reverses disabled voqWD config.
Hence the test was failing

config reload done as part of teardown:

sonic-mgmt/tests/snappi_tests/pfcwd/test_pfcwd_actions.py

Line 885 in 939485f

config_reload(sonic_host=duthost, config_source='config_db', safe_reload=True)

How did you do it?

Disabling the voqWD in the test case where PFCWD is disabled and traffic is sent for > 1min

How did you verify/test it?
