Blinking Lights in Network Devices - Common Mistakes and New APIs

Explore the challenges and solutions surrounding LED configuration in network devices in this 17-minute conference talk from the Linux Plumbers Conference. Delve into the recurring issues with RJ45 Ethernet socket LEDs and front panel indicators on various network devices. Examine the existing hacks in device trees for PHY LED configuration and understand why proposed patches have been rejected. Analyze the broader problem of repetitive mistakes in network driver development and learn strategies to avoid these issues when implementing new features. Gain insights into the recently added APIs for configuring PHY and MAC-driven LEDs, providing valuable information for driver writers and users looking to support and configure device LEDs effectively.
