Phylink and SFP - Going Beyond 1G Copper PHYs

Explore the evolution of Ethernet MAC drivers beyond 1Gbps in this Linux Plumbers Conference talk. Delve into the limitations of phylib and the introduction of phylink API for controlling complex, dynamic, and hot-pluggable PHYs. Learn about the differences between phylib and phylink, and discover the process of converting MAC drivers to utilize phylink's new features. Gain insights into kernel support for SFP modules, including handling hot-plugging of copper and fiber PHYs. Understand the challenges and solutions for managing high-bandwidth interfaces, SERDES interfaces, and fiber optical modules in modern network architectures.
