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

net: airoha: Introduce ethernet support for EN7581 SoC

2024-07-14T14:46:53Z

Add airoha_eth driver in order to introduce ethernet support for Airoha EN7581 SoC available on EN7581 development board (en7581-evb). EN7581 mac controller is mainly composed by the Frame Engine (PSE+PPE) and QoS-DMA (QDMA) modules. FE is used for traffic offloading (just basic functionalities are currently supported) while QDMA is used for DMA operations and QOS functionalities between the mac layer and the external modules conncted to the FE GDM ports (e.g MT7530 DSA switch or external phys). A general overview of airoha_eth architecture is reported below: ┌───────┐ ┌───────┐ │ QDMA2 │ │ QDMA1 │ └───┬───┘ └───┬───┘ │ │ ┌───────▼─────────────────────────────────────────────▼────────┐ │ │ │ P5 P0 │ │ │ │ │ │ │ ┌──────┐ │ P3 ├────► GDM3 │ │ │ └──────┘ │ │ │ │ ┌─────┐ │ │ │ PPE ◄────┤ P4 PSE │ └─────┘ │ │ │ │ │ │ │ │ ┌──────┐ │ P9 ├────► GDM4 │ │ │ └──────┘ │ │ │ │ │ │ │ P2 P1 │ └─────────┬───────────────────────────────────────────┬────────┘ │ │ ┌───▼──┐ ┌──▼───┐ │ GDM2 │ │ GDM1 │ └──────┘ └──┬───┘ │ ┌────▼─────┐ │ MT7530 │ └──────────┘ Currently only hw LAN features (QDMA1+GDM1) are available while hw WAN (QDMA2+GDM{2,3,4}) ones will be added with subsequent patches introducing traffic offloading support.

net: ethernet: mtk_eth_soc: switch to external PCS driver

2023-03-21T02:48:35Z

Now that we got a PCS driver, use it and remove the now redundant PCS code and it's header macros from the Ethernet driver. Signed-off-by: Daniel Golle Tested-by: Frank Wunderlich Reviewed-by: Russell King (Oracle) Signed-off-by: Jakub Kicinski

net: ethernet: mtk_wed: introduce wed wo support

2022-11-11T08:09:32Z

Introduce WO chip support to mtk wed driver. MTK WED WO is used to implement RX Wireless Ethernet Dispatch and offload traffic received by wlan nic to the wired interface.

net: ethernet: mediatek: Remove -Warray-bounds exception

2022-10-07T07:49:29Z

GCC-12 emits false positive -Warray-bounds warnings with CONFIG_UBSAN_SHIFT (-fsanitize=shift). This is fixed in GCC 13[1], and there is top-level Makefile logic to remove -Warray-bounds for known-bad GCC versions staring with commit f0be87c42cbd ("gcc-12: disable '-Warray-bounds' universally for now"). Remove the local work-around. [1] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105679 Signed-off-by: Kees Cook Signed-off-by: David S. Miller

eth: mtk_eth_soc: silence the GCC 12 array-bounds warning

2022-05-22T21:21:11Z

GCC 12 gets upset because in mtk_foe_entry_commit_subflow() this driver allocates a partial structure. The writes are within bounds. Silence these warnings for now, our build bot runs GCC 12 so we won't allow any new instances. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

net: ethernet: mtk_eth_soc: add support for Wireless Ethernet Dispatch (WED)

2022-04-06T13:08:49Z

The Wireless Ethernet Dispatch subsystem on the MT7622 SoC can be configured to intercept and handle access to the DMA queues and PCIe interrupts for a MT7615/MT7915 wireless card. It can manage the internal WDMA (Wireless DMA) controller, which allows ethernet packets to be passed from the packet switch engine (PSE) to the wireless card, bypassing the CPU entirely. This can be used to implement hardware flow offloading from ethernet to WLAN. Signed-off-by: Felix Fietkau Signed-off-by: David S. Miller

net: ethernet: mtk_eth_soc: add flow offloading support

net: ethernet: mtk_eth_soc: add support for initializing the PPE

2021-03-24T19:48:39Z

The PPE (packet processing engine) is used to offload NAT/routed or even bridged flows. This patch brings up the PPE and uses it to get a packet hash. It also contains some functionality that will be used to bring up flow offloading. Signed-off-by: Felix Fietkau Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S. Miller
