Bootlin at Netdev 0x17, THE Technical Conference on Linux Networking

VancouverBootlin will be at the Netdev 0x17 conference, subtitled THE Technical Conference on Linux Networking. It is indeed one of the major event for developers working on the networking side of the Linux kernel to gather and discuss current and future topics. This year, the conference will take place from Oct 30 to Nov 3 in Vancouver, Canada.

Bootlin is involved in a number of Linux kernel networking developments: development and/or improvement of Linux kernel drivers for Ethernet MACs, Ethernet PHYs, WiFi chips, support for SFP, for Ethernet switches, for PTP offloading, for MACsec offloading, improvements to the 802.15.4 stack, and more. As such, it is very relevant for us to meet the Linux kernel networking community, present our work, and understand where things are heading to in the networking stack.

Our engineers Maxime Chevallier and Alexis Lothoré will both attend the conference. In addition, Maxime will be presenting a talk titled Improving multi-phy and multi-port interfaces:

This talk will describe current use-cases where one MAC is connected to multiple PHYs (chained, or in parallel) and multiple front-facing ports, either through multiple PHYs or through a single multi-port PHY. There exist support for some of these scenarios already, but it is limited by the fact that the PHY device is hidden behind a net_device from userspace’s point of view. We therefore can’t configure an individual PHY when multiple PHYs are present on a link (through SFP transceivers for example), and selecting which front-facing port to use is also limited. This talk will describe ongoing work to support these complex topologies, the challenges faced and expected improvements.

We look forward to attending this event in a few weeks time!
