Merge branch 'introduce-flowtable-hw-offloading-in-airoha_eth-driver'
Lorenzo Bianconi says:
====================
Introduce flowtable hw offloading in airoha_eth driver
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).
