Time-Sensitive Networking (TSN) with Mainline Embedded Linux
summary
Shows how mainline Linux implements TSN end-to-end: use the TC subsystem and tc utility to configure Credit-Based Shaper (CBS), queueing via ETF / TXTIME and gate control with taprio, map SO_PRIORITY to VLAN PCP and hardware queues (device-tree for five TX queues), and run Linux PTP so PHC sync stays under ~100 ns RMS. Demonstrates GStreamer/ALSA AVTP plugins (GStreamer ≥1.18), benchmarks time sync and AVB talker/listener on i210 (igb) and DesignWare EQoS (stmmac) hardware with live demos.
