Add ASIC-based skip condition for generic_config_updater/test_srv6

[StormLiangMS]

Description of PR

Summary:
Add ASIC-based skip conditions for generic_config_updater/test_srv6 tests to prevent failures on platforms that do not support SRv6. The existing skip condition only covers topology (t0-isolated-d96u32s2), but SRv6 config updater tests also fail on older ASICs (Broadcom TH/TH2/TD3, Mellanox SPC1-3) because applying SRv6 CONFIG_DB entries triggers SAI errors caught by the loganalyzer during teardown.

Type of change

• Bug fix
• Testbed and Framework(new/improvement)
• New Test case
  • Skipped for non-supported platforms
• Test case improvement

Approach

What is the motivation for this PR?

Kusto data from 202511 .17 image (20251110.17) shows 122 out of 137 test runs of generic_config_updater/test_srv6 failed. All failures occurred on non-SRv6-capable ASICs:

The regression grew across image versions: .15 had 0 failures, .16 had 4 failures, .17 had 122 failures due to broader platform test coverage.

PR #21713 adds similar ASIC-based skip conditions for srv6/test_srv6_dataplane.py but misses generic_config_updater/test_srv6. PR #23226 adds loganalyzer ignore for SRv6 SAI errors but doesn't address the root cause of running SRv6 config tests on unsupported platforms.

How did you do it?

Updated tests/common/plugins/conditional_mark/tests_mark_conditions.yaml to add ASIC-based skip conditions for generic_config_updater/test_srv6:

• Skip for unsupported ASIC types (not mellanox/broadcom/cisco/vs)
• Skip for Mellanox SPC1/SPC2/SPC3 (only SPC4+ supports SRv6)
• Skip for Broadcom non-TH5 (only TH5+ supports SRv6)
• Keep existing topology skip for t0-isolated-d96u32s2

The conditions use OR logic (skip if ANY condition matches) and follow the same pattern as srv6/test_srv6_dataplane.py skip conditions.

How did you verify/test it?

• Cross-referenced Kusto failure data across .15, .16, and .17 images
• Verified all 122 failures occur on ASICs that match the new skip conditions
• Confirmed passing platforms (TH5, SPC4+, Cisco Q200/Q201L) are NOT matched by skip conditions
• YAML syntax validated

Any platform specific information?

Platforms affected (will now be skipped):

• Broadcom TH, TH2, TD3 (all models)
• Mellanox SPC1, SPC2, SPC3 (all models)

Platforms NOT affected (will continue to run):

• Broadcom TH5+
• Mellanox SPC4+
• Cisco Q200, Q201L
• VS (virtual switch)

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

@StormLiangMS Can you exclude th6 and q3d in Broadcom's skip condition too? Thanks.

There is a skip condition for it already:

hi @markx-arista I merged this to stop bleeding, could you file a PR for this unskip?
