Description of PR

Summary:
Fixes #

Type of change

Back port request

Approach

What is the motivation for this PR?

The tgen_port_info was added as part of Snappi test infra improvement, which enabled users to select between static (from variables.override.yml) and dynamic (select 100 and 400Gbps ports) ports.

This was NOT included in test_tx_drop_counter and test_global_pause test-scripts under snappi_tests/pfc section.

How did you do it?

Imported the tgen_port_info from snappi_fixtures.py and removed any reference to old setup_dut_port function for both test-scripts.

How did you verify/test it?

Verified the same on multi-DUT platform. As part of verification, test#1 runs on 1 RTR interface and 1 port-channel. test#2 runs on both portchannel interfaces.

…nter and global_pause test-script (#22490) Description of PR Added support for tgen_port_info in: tests/snappi_tests/pfc/test_global_pause_with_snappi.py tests/snappi_tests/pfc/test_tx_drop_counter_with_snappi.py Summary: Fixes # (issue) Type of change Bug fix Testbed and Framework(new/improvement) New Test case Skipped for non-supported platforms Test case improvement Back port request 202205 202305 202311 202405 202411 202505 202511 Approach What is the motivation for this PR? The tgen_port_info was added as part of Snappi test infra improvement, which enabled users to select between static (from variables.override.yml) and dynamic (select 100 and 400Gbps ports) ports. This was NOT included in test_tx_drop_counter and test_global_pause test-scripts under snappi_tests/pfc section. How did you do it? Imported the tgen_port_info from snappi_fixtures.py and removed any reference to old setup_dut_port function for both test-scripts. How did you verify/test it?

…nter and global_pause test-script (sonic-net#22490) Description of PR Added support for tgen_port_info in: tests/snappi_tests/pfc/test_global_pause_with_snappi.py tests/snappi_tests/pfc/test_tx_drop_counter_with_snappi.py Summary: Fixes # (issue) Type of change Bug fix Testbed and Framework(new/improvement) New Test case Skipped for non-supported platforms Test case improvement Back port request 202205 202305 202311 202405 202411 202505 202511 Approach What is the motivation for this PR? The tgen_port_info was added as part of Snappi test infra improvement, which enabled users to select between static (from variables.override.yml) and dynamic (select 100 and 400Gbps ports) ports. This was NOT included in test_tx_drop_counter and test_global_pause test-scripts under snappi_tests/pfc section. How did you do it? Imported the tgen_port_info from snappi_fixtures.py and removed any reference to old setup_dut_port function for both test-scripts. How did you verify/test it? Verification on 202511 is present in pull-request sonic-net#22380.
