10gbe KR Auto Negotiation

Question asked by jaydevshelat on Jun 5, 2019

Has Anyone achieved successful auto negotiation with 10gbe KR link? 

 

My System info:

  • AMD SoC Seatlle (Opteron A1100)
  • Ethernet Link Partner = Intel FPGA
  • OS: Debian/Ubuntu. I have downloaded & installed latest Linux Kernel (ver 5.15) -- which has all the latest fixes for the amd-xgbe driver.

 

Observation:  AN never completes -- both link partners stay stuck in Auto Negotiation Phase. From the FPGA I can see that  AMD chip is not sending the DME packets. FPGA is seen to be sending different packets. 

 

Any help / suggestion from anyone will be super helpful. 

 

Thank You in advance!
