net: airoha: Add FLOW_CLS_STATS callback support

2025-05-21T03:00:51Z

Introduce per-flow stats accounting to the flowtable hw offload in the airoha_eth driver. Flow stats are split in the PPE and NPU modules: - PPE: accounts for high 32bit of per-flow stats - NPU: accounts for low 32bit of per-flow stats FLOW_CLS_STATS can be enabled or disabled at compile time.

net: airoha: Introduce Airoha NPU support

2025-03-04T12:22:09Z

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. The airoha_eth driver can enable hw acceleration of learned 5-tuples rules if the user configure them in netfilter flowtable (netfilter flowtable support will be added with subsequent patches). 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. Introduce basic support for Airoha NPU module. Tested-by: Sayantan Nandy Signed-off-by: Lorenzo Bianconi Signed-off-by: Paolo Abeni

net: airoha: Move airoha_eth driver in a dedicated folder

2025-03-04T12:22:08Z

The airoha_eth driver has no codebase shared with mtk_eth_soc one. Moreover, the upcoming features (flowtable hw offloading, PCS, ..) will not reuse any code from MediaTek driver. Move the Airoha driver in a dedicated folder. Signed-off-by: Lorenzo Bianconi Signed-off-by: Paolo Abeni
