What I did
-Modified the MACsec orchestration logic to conditionally include or exclude the ability to match the SCI in ACL configurations based on the ASIC's capabilities.
-Implemented a capability check in SONiC to determine whether the SAI_ACL_TABLE_ATTR_FIELD_MACSEC_SCI attribute is supported by the ASIC, thus ensuring that neither SAI_ACL_TABLE_ATTR_FIELD_MACSEC_SCI nor SAI_ACL_ENTRY_ATTR_FIELD_MACSEC_SCI is used when unsupported.
Why I did it
The current implementation attempts to use the SAI_ACL_ENTRY_ATTR_FIELD_MACSEC_SCI attribute even when it's not supported by the underlying ASIC or driver, causing failures in the vendor's SAI/SDK code.
The capability check prevents these errors, ensuring compatibility with different hardware.
How I verified it
Compiled the code successfully without errors.
Conducted manual tests on Marvell platforms without support for the SAI_ACL_TABLE_ATTR_FIELD_MACSEC_SCI attribute to validate the conditional logic.
