I.x8dxp paired with 88E6172 issues

[jack_huang1]

During the development of I.X8DXP platform products, the communication could not be completed in the debugging of THE RGMII interface connection Marvel Switch communication.The switch model is 88E6172.The switch hardware configuration is correct, PHY PORT 0-4 is normal for external communication as the switch, and the RGMII interface cannot be configured successfully. Is there a driver with 88E6172 in I.MX8DXP?

Dear igorpadykov：

          At present, i.mx8dxp has received the broadcast network packet, but its IP address cannot be confirmed. Tcpdump - I eth0-v | grep 244 is executed on i.mx8dxp, please see the screenshot.      

          The configuration instructions used are as follows：    

Ping 192.169.5.227 on another COMPUTER on the LAN: 192.169.5.244, the problem is that it cannot confirm its IP address.

Please analyze the reasons and see how to solve them.Thank you very much.

       Best regards.
