Approach

What is the motivation for this PR?

PR##14912 has introduced single quotes around github issue url and this is causing conditional mark evaluation to fail. Thus conditional mark config is not honored and couple of tests are getting scheduled even though they are supposed to be skipped.

How did you do it?

Removed those unnecessary single quotes around the url.

How did you verify/test it?

Ran generic_config_updater/test_eth_interface.py::test_replace_fec and it's getting skipped correctly on Arista-7260CX3-D108C8 platform (currently it's getting scheduled and failing due to PR#14912).

Any platform specific information?

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