…csec_supported fix Why I did it On gearbox ports, creating MACsec on the PHY switch fails with SAI_STATUS_NOT_IMPLEMENTED if the gearbox PHY lacks a MACsec engine. A fix for this issue has already been committed. This PR aims to create the corresponding test case to validate that fix. How I did it Have added three testcases: - test_macsec_phy_switch_default: This tests the scenario when the macsec_supported field is absent in the gearbox_config.json - test_macsec_phy_switch_explicit: This tests the scenario when the macsec_supported field is set as true in the gearbox_config.json - test_macsec_npu_switch: This tests the scenario when the macsec_supported field is set as false in the gearbox_config.json Some helpers functions: - verify_macsec_in_asic_db: This verifies if the ASIC_DB has the required entries created or not. - verify_macsec_in_gb_asic_db: This verifies if the GB_ASIC_DB has the required entries created or not. - setup_gearbox_table: The job of this function is change the value of macsec_supported field. It modifies the value as per the requirement of the testcase. It writes the file gearbox_config.json - enable_macsec_on_port: Helper function to enable macsec. - cleanup_macsec: Helper function to delete macsec configuration.

What I did
Introduce a platform capability flag in the gearbox config to determine, per PHY, whether MACsec is supported (applies to all ports mapped to that PHY). MACsec orchestration will:
Have added three DVS testcases:
test_macsec_phy_switch_default: This tests the scenario when the macsec_supported field is absent in the gearbox_config.json
test_macsec_phy_switch_explicit: This tests the scenario when the macsec_supported field is set as true in the gearbox_config.json
test_macsec_npu_switch: This tests the scenario when the macsec_supported field is set as false in the gearbox_config.json
Why I did it
On gearbox ports, creating MACsec on the PHY switch fails (SAI_STATUS_NOT_IMPLEMENTED) if gearbox PHY does not have the MACsec engine.
How I verified it
Manually verified on DUT by adding macsec_supported=false in gearbox_config.json and configuring the macsec on the PHY port. Also ran the dvs testcase and made sure it is passing
