Eventually this series will be split in multiple ones once we drop the RFC. The Microchip LAN966X is a compact and cost-effective, multi-port Gigabit AVB/TSN Ethernet Switches with two integrated 10/100/1000BASE-T PHYs and a 600 MHz ARM Cortex A7 CPU subsystem. The LAN966X includes eight ports. In addition to the two integrated PHYs, the lAN966X supports up to 2 RGMII/RMII, up to 3 1000BASE-X/SerDes/ 2.5GBASE-X/KX, and up to 2 Quad-SGMII/Quad-USGMII interfaces. The LAN966X fully supports the IEEE family of Audio Video Bridging (AVB) and Time Sensitive Networking (TSN) standards, including the current IEC/IEEE draft 60802 TSN profile, which in concert provide high Quality of Service (QoS) for latency sensitive traffic streams over Ethernet. The LAN966X supports TSN domain protection though IEEE 802.1Qci Per Stream Filtering and Policing, advanced classification rules, and tunneling by adding VLAN tags. Each egress port supports eight priorities. Prior to scheduling, traffic can be shaped using dual-leaky bucket shaping, IEEE 802.1Qav Credit Based Shaping, and IEEE 802.1Qbv Time Aware Shaping, thus also supporting IEEE 802.1Q Enhanced Transmission Selection. Low latency is possible though latency optimized architecture, cut-through, and IEEE 802.1Qbu/802.3br Preemption. For higher traffic availability, the LAN966X supports Multiple Spanning Tree, IEEE 802.1CB Frame Replication and Elimination for Redundancy, IEC 62439-2 MRP, ODVA DLR, in addition to ITU-T G.8031 and G.8032 linear and ring protection. The LAN966X supports IEEE 802.1AS-2020 (gPTP) and IEEE 1588-2019 (PTP) time synchronization with time stamping in multiple domains in support of Working Clock and Global Time distribution. The LAN966X can operate either as a standalone switch or as a system co-processor with an external host CPU. The external host can manage the switch via PCIe or an Ethernet port. This series provides support for: - support for integrated PHY - host mode providing register based injection and extraction More support will be added in future patches.
