Harini Katakam focused on enhancing network driver stability in the analogdevicesinc/linux repository, addressing a critical issue in the MACB driver’s PCS selection logic. Working primarily in C and leveraging expertise in device drivers and embedded systems, Harini implemented a targeted fix to ensure the correct PCS is selected for both 10GBaseR and 1000BaseX interfaces. This adjustment resolved RGMII test failures and improved cross-speed interoperability, directly impacting NIC PHY negotiation reliability. The work demonstrated a deep understanding of network interface drivers and contributed to more stable Ethernet performance in both test and production environments, reducing test regressions and improving overall reliability.
