Thank you for contacting Intel Embedded Community.
In order to be on the same page, could you please tell me where you obtain the cited driver?
By the way, could you please confirm us if this forum is related to the Xeon D-1539 integrated 10Gb phy power thread?
Waiting for your reply to these questions.
The driver is version 5.3.7 as downloaded from Download Intel® Network Adapter Driver for PCIe* Intel® 10 Gigabit Ethernet Network Connections Under Linux*
Yes it is related and we are in contact with both the board manufacturer as well as the KR endpoint manufacturer. So far the endpoint manufacturer is saying that we need to find a way to improve the link from the Intel side (as shown in eye diagrams they helped generate). I'm looking for any and all knobs on the Intel side we can turn from the D-1539 to improve the link but am running into a lack of documentation (on misunderstanding of existing docs on my part).
