Distributed Switch Architecture: Running Mainline on Commercial Switches
summary
Distributed Switch Architecture (DSA) explains how to support commercial managed-switch ASICs in mainline Linux by upstreaming drivers and glue so the kernel natively handles VLANs, bridging and host ports using the DSA + switchdev stack. It covers working examples and demos for Realtek, Marvell, MediaTek and Microchip devices, showing boards booting via TFTP, firmware update paths, live forwarding with userspace control, and a live demo across ~70 switch devices proving traffic, management and updates work.
