[PATCH net-next v2 00/15] Introduce flowtable hw offloading in airoha_eth driver

[Lorenzo Bianconi]

> Introduce netfilter flowtable integration in airoha_eth driver to
> offload 5-tuple flower rules learned by the PPE module if the user
> accelerates them using a nft configuration similar to the one reported
> below:
> 
> table inet filter {
> 	flowtable ft {
> 		hook ingress priority filter
> 		devices = { lan1, lan2, lan3, lan4, eth1 }
> 		flags offload;
> 	}
> 	chain forward {
> 		type filter hook forward priority filter; policy accept;
> 		meta l4proto { tcp, udp } flow add @ft
> 	}
> }
> 
> Packet Processor Engine (PPE) module available on EN7581 SoC populates
> the PPE table with 5-tuples flower rules learned from traffic forwarded
> between the GDM ports connected to the Packet Switch Engine (PSE) module.
> airoha_eth driver configures and collects data from the PPE module via a
> Network Processor Unit (NPU) RISC-V module available on the EN7581 SoC.
> Move airoha_eth driver in a dedicated folder
> (drivers/net/ethernet/airoha).

Please ignore this series, I spotted a couple of issues. I will post v3 soon.

Regards,
Lorenzo
