Intel X710 in Server 2025 SET Team results in no connectivity

[PnoTK]

I purchased one of the new minisforum MS-A2s, hoping they could replace my TMM stack running Server 2025 with Hyper-V and SET teaming, as they have onboard 10Gb NICs. To my surprise, the NICs, when added to a SET team, will not pass any network traffic. If I take the same adapter(s) and create a simple vswitch, everything works, but I lose out on converged network teaming. I'm running the latest firmware from Intel ( 9.54 ) and the latest drivers for the X710 NICs via Intel.

I've tried SET teaming with a single adapter, both adapters, and different algorithms to no avail, and installed Data Center Bridging as well to see if that made any difference. 

I've seen similar posts online and even a lot of information about LLDP causing issues with these cards, but I have gone into the BIOS for each NIC and disabled the LLDP agent, and that didn't solve anything either.

In my research, I've found the following:

This seems to be directly related to my problem, but no solution: No SET-Switch Team possible on Intel X710 NICs? | Microsoft Community Hub

Intel says that in the 700 series, it's enabled in firmware by default, and in the MS-A2 BIOS, I can confirm it was set to enabled until I disabled it. Firmware Link Layer Discovery Protocol (FW-LLDP) - 30.3 - ID:705831 | Intel® Ethernet Adapters and Devices User Guide

Disabling the LLDP agent for other users, online, worked but in my case I haven't noticed a difference.

Hi PnoTK,

Thank you for your response.

Could you kindly confirm if the X710 was shipped along with the MS-A2 system or purchased separately?

If this card was purchased separately, please share front and back pictures of the network adapter with the product markings clearly visible.

Your prompt response will help us assist you more effectively.

It was shipped with the MS-A2 and an onboard device.

This turned out to be a driver issue with the latest Intel and even Dell's offerings.  Once I uninstalled the NICs in Device Manager and rediscovered them, Windows installed a driver from 2023, and SET is working correctly.
