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.
