Month: 2026-04 | Namiltd/OpenWrt: Delivered two high-impact fixes to Realtek PHY/MDIO and SMBus Rollball flows, improving hardware reliability and SFP compatibility. The changes address incorrect SMBus register access during Rollball operations and preserve MDIO address 0 during PHY initialization, reducing erroneous reads/writes and enabling stable network interfaces for SFP modules. Implemented via commits c78e2fe26dde403179da1622c4197e74a9f1cb93 and 45633073fe057b51d3c7397e28b6c5703c88686e. Impact: higher availability, lower maintenance, and smoother deployments. Technologies: SMBus, MDIO, Rollball protocol, Realtek RTL93xx drivers, OpenWrt patching.

February 2026 monthly summary for DragonBluep/openwrt. Delivered a significant RTL93xx driver enhancement to improve in-band auto-negotiation advertisement and restart capabilities. Implemented advertisement of current configuration for 1000Base-X and 2500Base-X, and added a SerDes operation to restart in-band negotiation to apply advertisement changes. This enables dynamic configuration changes without service disruption, improving flow control negotiation and reducing downtime during NIC reconfiguration. Commits: e3be4654a1f405985964d8b5e5add3c149f55fba (realtek: pcs: rtl93xx: configure in-band AN advertisement) and 6dae444ee94d05972c842e765daf01de0fe50ce5 (realtek: pcs: rtl93xx: implement restarting auto-negotiation).
