Adding Support for Power Over Ethernet to Linux Network Stack

Explore the integration of Power over Ethernet (PoE) support into the Linux network stack in this informative conference talk. Gain insights into PoE technology, its origins in IEEE Clause 33, and its practical applications for simplifying device installations. Examine the current state of PoE support in the Linux kernel and user space. Delve into the ongoing Linux implementation, including modifications to the PSE framework core and bindings to accommodate PoE specificities. Learn about the development of Linux kernel drivers for two PoE controllers: Microchip PD692x0 and Texas Instruments TPS23881. Discover the mainline status of PoE support in Linux, pending merges, and future development plans. Understand the role of the DENT Project in sponsoring and funding this crucial enhancement to the Linux network stack.
