Dear DPDK Dev .

This is PM from Advantech ENPD. We are working on Intel Amston Lake CPU’s  SGMII <> GPY215 PHY for DPDK test but fail.

We consulted with Intel support team and they suggested we should consult DPDK community and it should have the patch or code change for Amston Lake <> GYP215 available for DPDK.

Could you kindly suggest us the direction of it?  I also keep my Engineering team in this mail loop for further discussion.  

Thank you so much    

The error message while we testing DPDK
