Hi, David
The TC Flower Classifier allows control of packets based on flows
determined by matching of well-known packet fields and metadata.
Offload of the TC Flower classifier and related modules provides a
powerful mechanism to both increase throughput and reduce CPU
utilisation for users of such flow-based systems.
The command "ethtool -N" can provide similar function.
Now, hip08 SOC has flow classifier hardware offload capacity, which
tools we should support in HNS kernel driver?
Can you give some suggestion?
Regards
Wei Hu

Afaik ethtool settings is very limited to rx queue steering.
If you want more actions, like vlan modification, tunnels, forward, etc,
you should use tc-flower
