Features Supported

Controller Features

  • Support for MII, GMII, RGMII, SGMII, and 1000BASE-X PHY interfaces
  • Support for 1000BASE-X and SGMII over Select Input/Output (I/O) Low Voltage Differential Signaling (LVDS)
  • Support for pause frames for flow control
  • Media Independent Interface Management (also called as MII), is used for accessing the PHY registers
  • Ethernet Audio Video Bridging (AVB) support
  • AXI4-Stream transmit/receive interface
  • Support for 2.5G Ethernet. This feature is enabled for the following devices: Kintex®-7, Virtex®-7 with GTH and GTX transceivers Artix®-7 devices with GTP and speed grade -2 and -3 UltraScale™, UltraScale+™ devices with GTH and GTY transceivers
  • IEEE Standard 1588 Support
  • AXI4-Lite register interface

Standalone Driver Supported Features

The AXI Ethernet Standalone driver supports the below things.
  • Supports all 1G phy-interface types MII, GMII, RGMII, SGMII and 1000base-x
  • Supports VLAN Frames
  • Supports Pause frames and flow control features
  • Support for AXI DMA Ethernet-based designs
  • Support for Axi Ethernet FIFO based designs
  • Support for Axi MCDMA Ethernet-based designs
  • Supports different Speeds 10/100/1000 Mbps
  • Supports Partial/Full Checksum offloading
  • Supports 2.5G buffered mode feature.

Features not supported

  • IEEE 1588 feature is not supported
  • No Support when 2.5G Ethernet is configured for Non-Buffered/Processor mode
  • No Support when 1G Ethernet is configured in Non-Buffered/Processor Mode

Interop

- PHY device Marvell 88E1116 has been tested on KC705 evaluation board
- PHY device TI DP83867 SGMII have been tested on VCU118 board.

Test cases

Axi Ethernet DMA Example
Axi Ethernet basic AXI DMA loopback example can be tested by selecting xaxiethernet_example_intr_sgdma.c, xaxiethernet_example_util.c and xaxiethernet_example.h from the driver.
Refer to https://github.com/Xilinx/embeddedsw/blob/master/XilinxProcessorIPLib/drivers/axiethernet/examples/readme.txt for more information.

Axi Ethernet FIFO Example
Axi Ethernet basic AXI FIFO loopback example can be tested by selecting xaxiethernet_example_intr_fifo.c, xaxiethernet_example_util.c and xaxiethernet_example.h from the driver.
Refer to https://github.com/Xilinx/embeddedsw/blob/master/XilinxProcessorIPLib/drivers/axiethernet/examples/readme.txt for more information.

Known Issues/Limitations
  • At the h/w level if the MAC reference clock is driving from onboard clock oscillator e.g si570 or si5324. Make sure clock is programmed to the proper clock value before performing any operations on the MAC.
