[action] [PR:12944] Verify the PCIe daemon status before retrieving the PCIE_DEVICES table from the database

[mssonicbld]

Description of PR

Summary: The "get_pcie_devices_tbl_key" fixture is currently invoked before the "setup" fixture. When the PCIe daemon is not running, the "get_pcie_devices_tbl_key" fixture asserts that the PCIE_DEVICES table is empty in the database and causes the test to fail. Instead, make the "get_pcie_devices_tbl_key" fixture dependent on the "setup" fixture to verify the daemon status before retrieving the PCIE_DEVICES table from the database, which skips the test if daemon is not running.

Approach

What is the motivation for this PR?

There are occasional failures with the "PCIE_DEVICES table is empty" message when running PCIe tests. This fix ensures the PCIe daemon is running before retrieving the PCIE_DEVICES table, thereby increasing test reliability.

How did you do it?

Make the "get_pcie_devices_tbl_key" fixture dependent on the "setup" fixture to verify the daemon status before retrieving the PCIE_DEVICES table from the database.

How did you verify/test it?

• Ran test_pcied.py tests on lab testbeds.

Any platform specific information?

Supported testbed topology if it's a new test case?
