Link to the spec: ----------------- https://opensig.org/download/document/OPEN_Alliance_10BASET1x_MAC-PHY_Serial_Interface_V1.1.pdf - Adds driver support for Microchip LAN8650/1 Rev.B1 10BASE-T1S MACPHY Ethernet driver in the net/ethernet/microchip/lan865x/lan865x.c. Link to the product: -------------------- https://www.microchip.com/en-us/product/lan8650 Testing Details: ---------------- The driver performance was tested using iperf3 in the below two setups separately. Setup 1: -------- Node 0 - Raspberry Pi 4 with LAN8650 MAC-PHY Node 1 - Raspberry Pi 4 with EVB-LAN8670-USB USB Stick Setup 2: -------- Node 0 - SAMA7G54-EK with LAN8650 MAC-PHY Node 1 - Raspberry Pi 4 with EVB-LAN8670-USB USB Stick Achieved maximum of 9.4 Mbps. Some systems like Raspberry Pi 4 need performance mode enabled to get the proper clock speed for SPI.
