Documentation: networking: Fix missing PSE documentation and grammar issues

2024-09-14T02:59:53Z

Fix a missing end of phrase in the documentation. It describes the ETHTOOL_A_C33_PSE_ACTUAL_PW attribute, which was not fully explained. Also, fix grammar issues by using simple present tense instead of present continuous.

net/mlx5e: SHAMPO, Add no-split ethtool counters for header/data split

2024-09-13T03:50:30Z

When SHAMPO can't identify the protocol/header of a packet, it will yield a packet that is not split - all the packet is in the data part. Count this value in packets and bytes.

net: ena: Add ENA Express metrics support

2024-09-13T01:01:17Z

ENA Express metrics, called `ena_srd` are exposed to customers via `ethtool`. The metrics allow customers to check the configuration (mode), tx/rx counters as well as resource utilization. The documentation is also updated to provide a general explanation about ENA Express as well as links for further information about metrics and configurations.

dt-bindings: net: add Microchip's LAN865X 10BASE-T1S MACPHY

2024-09-12T03:53:46Z

The LAN8650/1 combines a Media Access Controller (MAC) and an Ethernet PHY to enable 10BASE-T1S networks. The Ethernet Media Access Controller (MAC) module implements a 10 Mbps half duplex Ethernet MAC, compatible with the IEEE 802.3 standard and a 10BASE-T1S physical layer transceiver integrated into the LAN8650/1. The communication between the Host and the MAC-PHY is specified in the OPEN Alliance 10BASE-T1x MACPHY Serial Interface (TC6).

Documentation: networking: add OPEN Alliance 10BASE-T1x MAC-PHY serial interface

2024-09-12T03:53:42Z

The IEEE 802.3cg project defines two 10 Mbit/s PHYs operating over a single pair of conductors. The 10BASE-T1L (Clause 146) is a long reach PHY supporting full duplex point-to-point operation over 1 km of single balanced pair of conductors. The 10BASE-T1S (Clause 147) is a short reach PHY supporting full / half duplex point-to-point operation over 15 m of single balanced pair of conductors, or half duplex multidrop bus operation over 25 m of single balanced pair of conductors. Furthermore, the IEEE 802.3cg project defines the new Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (Clause 148) meant to provide improved determinism to the CSMA/CD media access method. PLCA works in conjunction with the 10BASE-T1S PHY operating in multidrop mode. The aforementioned PHYs are intended to cover the low-speed / low-cost applications in industrial and automotive environment. The large number of pins (16) required by the MII interface, which is specified by the IEEE 802.3 in Clause 22, is one of the major cost factors that need to be addressed to fulfil this objective. The MAC-PHY solution integrates an IEEE Clause 4 MAC and a 10BASE-T1x PHY exposing a low pin count Serial Peripheral Interface (SPI) to the host microcontroller. This also enables the addition of Ethernet functionality to existing low-end microcontrollers which do not integrate a MAC controller.
