net: phy: add Applied Micro QT2025 PHY driver

2024-08-30T09:27:35+00:00

This driver supports Applied Micro Circuits Corporation QT2025 PHY, based on a driver for Tehuti Networks TN40xx chips. The original driver for TN40xx chips supports multiple PHY hardware (AMCC QT2025, TI TLK10232, Aqrate AQR105, and Marvell 88X3120, 88X3310, and MV88E2010). This driver is extracted from the original driver and modified to a PHY driver in Rust. This has been tested with Edimax EN-9320SFP+ 10G network adapter.

net: phy: dp83tg720: Add cable testing support

2024-08-16T17:16:26+00:00

Introduce cable testing support for the DP83TG720 PHY. This implementation is based on the "DP83TG720S-Q1: Configuring for Open Alliance Specification Compliance (Rev. B)" application note. The feature has been tested with cables of various lengths: - No cable: 1m till open reported. - 5 meter cable: reported properly. - 20 meter cable: reported as 19m. - 40 meter cable: reported as cable ok.

phy: Add Open Alliance helpers for the PHY framework

2024-08-16T17:16:26+00:00

Introduce helper functions specific to Open Alliance diagnostics, integrating them into the PHY framework. Currently, these helpers are limited to 1000BaseT1 specific TDR functionality.

net: phy: air_en8811h: Add the Airoha EN8811H PHY driver

2024-03-29T19:06:44+00:00

Add the driver for the Airoha EN8811H 2.5 Gigabit PHY. The phy supports 100/1000/2500 Mbps with auto negotiation only. The driver uses two firmware files, for which updated versions are added to linux-firmware already. Note: At phy-address + 8 there is another device on the mdio bus, that belongs to the EN881H. While the original driver writes to it, Airoha has confirmed this is not needed. Therefore, communication with this device is not included in this driver.

net: phy: nxp-c45-tja11xx: add MACsec support

2023-12-27T13:08:10+00:00

Add MACsec support. The MACsec block has four TX SCs and four RX SCs. The driver supports up to four SecY. Each SecY with one TX SC and one RX SC. The RX SCs can have two keys, key A and key B, written in hardware and enabled at the same time. The TX SCs can have two keys written in hardware, but only one can be active at a given time. On TX, the SC is selected using the MAC source address. Due of this selection mechanism, each offloaded netdev must have a unique MAC address. On RX, the SC is selected by SCI(found in SecTAG or calculated using MAC SA), or using RX SC 0 as implicit. Signed-off-by: Radu Pirea (NXP OSS) Signed-off-by: David S. Miller

rust: core abstractions for network PHY drivers

2023-12-15T09:35:50+00:00

This patch adds abstractions to implement network PHY drivers; the driver registration and bindings for some of callback functions in struct phy_driver and many genphy_ functions. This feature is enabled with CONFIG_RUST_PHYLIB_ABSTRACTIONS=y. This patch enables unstable const_maybe_uninit_zeroed feature for kernel crate to enable unsafe code to handle a constant value with uninitialized data. With the feature, the abstractions can initialize a phy_driver structure with zero easily; instead of initializing all the members by hand. It's supposed to be stable in the not so distant future.
