The new offloadable QoS features introduced in this patch series are: - tc-mqprio for mapping traffic class to hardware queue. Queues are by default mapped 1:1 in hardware, as such the mqprio qdisc is used as an attachment point for qdiscs tbf and ets. $ tc qdisc add dev eth0 root handle 1:0 mqprio - tc-tbf for setting up shaping on scheduler elements of the HSCH (Hierarchical Scheduler) block. Shaping on either port output or queue output is supported. Port shaper: $ tc qdisc add dev eth0 root handle 1:0 tbf rate \ 10000000 burst 8192 limit 1m Queue shaper: $ tc qdisc replace dev eth0 parent 1:5 handle 2:0 tbf \ rate 10000000 burst 8192 limit 1m - tc-ets for setting up strict and or bandwidth-sharing bands on one through eight priority queues. Configure a mix of strict and bw-sharing bands: $ tc qdisc add dev eth0 handle 1: root ets bands 8 strict 5 \ quanta 1000 1000 1000 priomap 7 6 5 4 3 2 1 0 Patch #1 Sets up the tc hook. Patch #2 Adds support for offloading the tc-mqprio qdisc. Patch #3 Adds support for offloading the tc-tbf qdisc. Patch #4 Adds support for offloading the tc-ets qdisc. Patch #5 Updates the maintainers of the sparx5 driver. ======================================================================== v1: https://lore.kernel.org/netdev/20220919120215.3815696-1-daniel.machon@microchip.com/ v1 -> v2: - Fix compiler warning in patch #2 - Fix comment style in patch #4 Daniel Machon (5): net: microchip: sparx5: add tc setup hook net: microchip: sparx5: add support for offloading mqprio qdisc net: microchip: sparx5: add support for offloading tbf qdisc net: microchip: sparx5: add support for offloading ets qdisc maintainers: update MAINTAINERS file.
