BSP-2022.09

UNG8309 is a carrier board for UNG8291 expanding the connectivity using the edge connector. The UNG8309 is supported by the lan966x_pcb8309.dts file. The UNG8291 includes 2 SFP ports, and this release also includes the needed fixes to use SFPs at speed up to 2.5Gb/s.

The LAN966x driver has been expanded with RGMII support. RGMII can be enabled in the devicetrees using existing DT-bindings.

TCAM support has been added to the Sparx5 driver. The driver supports the following HW resoruces: IS0/CLM, IS2, ES0 and ES2 (see the datasheet for details).

This feature can be utilized by using following user-space tools: - tc filter: Part of the tc-flower feature set. - vcap: user-space tool.

The vcap user-space tool is an extended feature using its own netlink interface and will not be upstream. vcap aims for supporting all features supported by HW. The tc filter is a stnadardlized interface supporting a subset of the features, and will eventually be submitted to the upstream kernel.

TAS - Time Aware Shaper support has been implemented in the Sparx5 driver. The TAS implementation can be configured using the taptio qdisc part of tc (see Time-Aware Scheduling section in the BSP-Doc or the tc-taprio man-page.

The Sparx5 driver has added support for the following schedullers and shapers:

FramePreemption supprot has been added. See the BSP-Doc page for details: Frame Preemption for details.

A new driver supporting the LAN8841 1G RGMII/GMII PHY is added. The driver has support for basic features, Link change interrupts, PTP/Timestamping, 1pps output and 1pps input.

The BSP-Doc covering LAN966x is now feature complete and ready for use. This release includes a new section on secure boot, and various small fixes in the existing content.

Sparx5 documentation is still in beta.
