Ethernet Switch Support in the Linux Kernel – Alexandre Belloni, Bootlin (formerly Free Electrons)

Hardware Ethernet switches are appearing on more SoC families and can take care of many network functionalities like VLAN tagging, IGMP snooping, link aggregation,… Linux is able to offload network processing to those switches using the switchdev and the DSA APIs.

This talk will introduce the Ethernet switches and their typical features, the Linux switchdev and DSA APIs and their differences. It will also give an overview of sample implementations and how to use the features from userspace.
