Solution
The PXIe-8238 uses the Intel 82599 10Gb ethernet controller. The card will work with the drivers available on the Intel web site.
As of June, 2025 the latest driver and Intel PROSet software are available at the following location:
Intel® Network Adapter Driver for Windows® 10
The location of the drivers may change, as this is an Intel site.
You will need to install both the driver and IntelPROSet. Once installed you should be able to configure Intel Teaming.
