Worked on the Telecominfraproject/wlan-ap repository to address a critical issue affecting 10G Ethernet support for the RTL8261N PHY. Delivered a targeted bug fix in C, updating the rtl826xb_get_features() function to ensure the ETHTOOL_LINK_MODE_10000baseT_Full_BIT remains set, which prevents unintended link mode clearance and enables stable high-speed connectivity. The solution was implemented as a concise patch series within the qca-wifi-7: ipq53xx: rtk_phy codebase, focusing on kernel driver development and embedded systems. This work improved network reliability for 10G deployments, demonstrating expertise in network programming, kernel debugging, and PHY layer feature handling.
