Approach

What is the motivation for this PR?

test_snmp_queue_counters.py is not a required feature on C0 topology. Add c0 to the topo_type skip list in tests_mark_conditions.yaml.

How did you do it?

Extended the existing skip condition for snmp/test_snmp_queue_counters.py:

• topo_type in ['m0', 'mx', 'm1'] → topo_type in ['m0', 'mx', 'm1', 'c0']
• Updated the accompanying reason string to mention C0.

How did you verify/test it?

Change is confined to conditional-mark yaml; no runtime code change. The upstream PR was merged to sonic-net/sonic-mgmt:master after review.

Any platform specific information?

None — topology-based skip.

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

N/A (existing test).

Cherry-pick notes

Upstream cherry-pick to msft-202603 conflicted (label Cherry Pick Conflict_msft-202603 was applied on the upstream PR). Root cause: master already contains an unrelated Mellanox #17929 skip condition for the same test that hasn't been ported to 202603. This cherry-pick keeps only the PR 25946 intent (adding c0 to the skip list) and does not pull in the unrelated Mellanox condition.
