When was ULP (Ultra Low Power Mode) implemented for Intel Ethernet Adapters for the first time

It seems that Intel has implemented the ULP (Ultra Low Power Mode) for its Ethernet products since long time ago. For example, In I218 datasheet https://www.mouser.com/datasheet/2/612/i218-ethernet-connection-datasheet-275854.pdf, I can find  ULP related revision history:

2.2   September 2013  

• Revised section 6.3.1.4.2 (EEE LPI Unsupported Features; added network proxy offload bullet).

• Revised section 6.4 (The Intel® Ethernet Connection I218 Ultra Low Power (ULP); LED tri-state mode bullet).

 

The earlier products like I210-LM may support ULP as well. But just want to know when was ULP (Ultra Low Power Mode) implemented for Intel Ethernet Adapters for the first time. Thanks!

Hello hellolwl,


Thank you for posting in Intel Ethernet Communities. 


We hope you don't mind providing below information before we further check your request. 

1. Can you share the reason why would you like to know when was ULP (Ultra Low Power Mode) implemented for Intel Ethernet Adapters for the first time? This is just for our record purposes

2. When you mentioned 'Intel Ethernet Adapters', are you implying to all of Intel Ethernet Controllers(LAN on motherboard(LOM)) and Adapters (PCIe adapters)


Looking forward to your reply. 


Should there be no response from you, I’ll make sure to reach out after 3 business days.

Hi Crisselle,

 

Thanks for the response! And sorry for replying to you later!

 

1. I can't disclose the details. But we notice some differences in the transition states in terms of port speed when ULP is enabled/disabled. And it may cause some interoperability issue in port speed negotiation.

 

2. I was implying to all of Intel Ethernet Controllers.

 

Thanks again!
