During March 2026, Darius focused on improving test reliability in the sonic-net/sonic-mgmt repository by fixing the VOQ drop counter test verification for Q3D single-ASIC platforms. He addressed a bug where the test’s previous method of toggling SFI ports to induce credit starvation did not accurately reflect hardware behavior. Instead, Darius implemented a hardware register-based trigger using Python, aligning the test with actual device operation and ensuring correct VOQ-level counter validation for Ethernet-IB links. By removing dependencies on bcmcmd -n for single-ASIC systems while preserving multi-ASIC logic, he enhanced cross-platform test consistency and maintainability through detailed code updates.
