The Intel i226 Ethernet Controller is a PCIe Gen 2 one-lane modular endpoint device that integrates a GbE Media Access Control (MAC) and Physical Layer (PHY) port. This driver provides support for MAC and DMA-specific initialization and runtime TX/RX operations. Key features: - MSI-X interrupts for TX/RX DMA channels. - Multiple TX/RX DMA channel support with exclusive bottom-half. - Implements a circular descriptor ring architechture with producer-consumer semantics for high performance pkt processing. - Full duplex support for 10/100/1000 Mbps. - Half duplex support for 10/100 Mbps. - Auto-negotiation for 10/100/1000 Mbps. - MTU customization for flexible packet sizes. - MAC address filtering based on: - Random MAC generation. - Local-mac-address mentioned in device tree. - EEPROM pre-programmed mac address. - Setting mac address via net shell. - Support for multiple Ethernet interface instances.
