net: ethernet: Remove accidental duplication in Kconfig file

2025-03-08T03:42:26Z

Commit fb3dda82fd38 ("net: airoha: Move airoha_eth driver in a dedicated folder") accidentally added the line: source "drivers/net/ethernet/mellanox/Kconfig" in drivers/net/ethernet/Kconfig, so that this line is duplicated in that file. Remove this accidental duplication.

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

ethernet: Make OA_TC6 config symbol invisible

2024-12-15T21:49:33Z

Commit aa58bec064ab1622 ("net: ethernet: oa_tc6: implement register write operation") introduced a library that implements the OPEN Alliance TC6 10BASE-T1x MAC-PHY Serial Interface protocol for supporting 10BASE-T1x MAC-PHYs. There is no need to ask the user about enabling this library, as all drivers that use it select the OA_TC6 symbol. Hence make the symbol invisible, unless when compile-testing.

net: ethernet: oa_tc6: implement register write operation

2024-09-12T03:53:42Z

Implement register write operation according to the control communication specified in the OPEN Alliance 10BASE-T1x MACPHY Serial Interface document. Control write commands are used by the SPI host to write registers within the MAC-PHY. Each control write commands are composed of a 32 bits control command header followed by register write data. The MAC-PHY ignores the final 32 bits of data from the SPI host at the end of the control write command. The write command and data is also echoed from the MAC-PHY back to the SPI host to enable the SPI host to identify which register write failed in the case of any bus errors. Control write commands can write either a single register or multiple consecutive registers. When multiple consecutive registers are written, the address is automatically post-incremented by the MAC-PHY. Writing to any unimplemented or undefined registers shall be ignored and yield no effect.

net: ethernet: remove duplicated CONFIG_SUNGEM_PHY entry

2024-02-07T13:17:51Z

Both drivers/net/Kconfig and drivers/net/ethernet/Kconfig contain the same config entry: config SUNGEM_PHY tristate Commit f860b0522f65 ("drivers/net: Kconfig and Makefile cleanup") moved SUNGEM_PHY from drivers/net/Kconfig to drivers/net/ethernet/Kconfig. Shortly after it was applied, commit 19e2f6fe9601 ("net: Fix sungem_phy sharing.") added the second one to drivers/net/Kconfig. I kept the one in drivers/net/Kconfig because this CONFIG option controls the compilation of drivers/net/sungem_phy.c. Signed-off-by: Masahiro Yamada Reviewed-by: Simon Horman Signed-off-by: David S.

net: restore alpha order to Ethernet devices in config

2023-03-10T07:36:28Z

The filename "wangxun" sorts between "intel" and "xscale", but xscale/Kconfig contains "Intel XScale" prompts, so Wangxun ends up in the wrong place in the config front-ends. Move wangxun/Kconfig so the Wangxun devices appear in order in the user interface.

net: ethernet: adi: Add ADIN1110 support

2022-09-20T13:00:30Z

The ADIN1110 is a low power single port 10BASE-T1L MAC-PHY designed for industrial Ethernet applications. It integrates an Ethernet PHY core with a MAC and all the associated analog circuitry, input and output clock buffering. ADIN1110 MAC-PHY encapsulates the ADIN1100 PHY. The PHY registers can be accessed through the MDIO MAC registers. We are registering an MDIO bus with custom read/write in order to let the PHY to be discovered by the PAL. This will let the ADIN1100 Linux driver to probe and take control of the PHY. The ADIN2111 is a low power, low complexity, two-Ethernet ports switch with integrated 10BASE-T1L PHYs and one serial peripheral interface (SPI) port. The device is designed for industrial Ethernet applications using low power constrained nodes and is compliant with the IEEE 802.3cg-2019 Ethernet standard for long reach 10 Mbps single pair Ethernet (SPE). The switch supports various routing configurations between the two Ethernet ports and the SPI host port providing a flexible solution for line, daisy-chain, or ring network topologies. The ADIN2111 supports cable reach of up to 1700 meters with ultra low power consumption of 77 mW. The two PHY cores support the 1.0 V p-p operating mode and the 2.4 V p-p operating mode defined in the IEEE 802.3cg standard. The device integrates the switch, two Ethernet physical layer (PHY) cores with a media access control (MAC) interface and all the associated analog circuitry, and input and output clock buffering. The device also includes internal buffer queues, the SPI and subsystem registers, as well as the control logic to manage the reset and clock control and hardware pin configuration. Access to the PHYs is exposed via an internal MDIO bus. Writes/reads can be performed by reading/writing to the ADIN2111 MDIO registers via SPI. On probe, for each port, a struct net_device is allocated and registered. When both ports are added to the same bridge, the driver will enable offloading of frame forwarding at the hardware level. Driver offers STP support. Normal operation on forwarding state. Allows only frames with the 802.1d DA to be passed to the host when in any of the other states. When both ports of ADIN2111 belong to the same SW bridge a maximum of 12 FDB entries will offloaded by the hardware and are marked as such.
