Tristram Ha
Tristram Ha expanded Linux kernel support for Microchip KSZ switches in the geerlingguy/linux repository, focusing on both new feature integration and critical bug fixes. He added KSZ8463 support to the DSA driver, implementing device-tree bindings, SPI access, register mappings, and MAC address programming in C and yaml to improve hardware compatibility and telemetry accuracy. Tristram also addressed reset reliability and MAC table clearing for KSZ8863/KSZ8873 devices, and corrected HSR port membership handling for KSZ9477 switches. His work demonstrated deep kernel development expertise, precise register-level updates, and a strong understanding of embedded systems and network driver reliability.
