hi i got a pc card with 82599EN on it
I think the datasheet sais it supports 10GBase-KR
This would be nice, since my PHY I want to talk to only understands this and some Fiber-stuff..
why the ethtool doesnt show 10GBase-KR ? It shows all other protocols like SR and LR..
I also have a NIC with X710-BM2 ...
but it also doesnt show me something...
and second question: DAC -cable would work right?
someone has an idea?
Maybe base 1000 X shown in ethtool of my NIC is compatible ... i found:
The first formal standard for backplane Ethernet was created not by the IEEE, but by PICMG. The PICMG 3.1
specification includes a definition for 1000BASE-BX, which is essentially identical to the 1000BASE-X already
defined for optical Gigabit Ethernet. This standard does not include many of the typical features of Ethernet,
such as auto-negotiation. Nonetheless, it was widely adopted and was incorporated into other standards, such
as VITA 65 (OpenVPX).
In 2007, the IEEE ratified 802.3ap, which provides physical layer standards for Ethernet over electrical backplanes.
The 1000BASE-KX standard incorporates the 1000BASE-X layer, but also adds a scheme for auto-negotiation
and compatibility with other backplane Ethernet links. 1000BASE-KX can typically be made interoperable with
1000BASE-BX or 1000BASE-X by disabling auto-negotiation."
Thank you for posting in Intel Ethernet Communities.
Before we proceed, let me clarify if you are designing a board or a system with embedded 82599EN?
If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.

thank you for your answer. Its maybe just more a general question about Ethernet. I have already a finished NIC with a 82599EN inside.I have have A external PHY-device I want to connect with this NIC. Also using SFP+ 10GBase-T. The PHY only supports SR,LR nad KR and some other fiber. What should I look for when I do this? Will the transceiver translate it correctly and everything is fine?
Base on your inquiry, we have specific forum for these issues and I will be transferring this thread for faster response.
Please wait for their reply within 1 to 2 business days.
Thank you and stay safe.

Thank you for contacting Intel Embedded Community.
Based on your previous communication, we want to address the following questions:
Could you please clarify if the design related to this situation has been designed by you or by a third-party company?
Could you please let us know in case it is a third-party design the name of the manufacturer, model, and where to find the information related to the affected design?
Could you please list the sources that you used to implement the affected design and if it has been verified by Intel?
We are waiting for your answer to these questions.

Thanks for your reply.
Based on the provided information, you should contact the manufacturers of the affected devices because we do not have the information about their implementations to give you support.
You should contact them as a reference using the channels listed on the following websites:
yeah I first talked to them. They didn't know exactly -even said that they are not compatible. I asked if they have another NIC for Ethernet KR... they said yes they have only one.
Maybe the whole issue is just because i dont understand the Ethernet standards: I just want to be sure if this works: phy(10gbase kr ) -> SFP+ ->DAC-> SFP+-> 10GbE NIC( some standard)
