Intel Network Adapter PROSet Package 26.1 for Windows 10 64-bit

The Microsoft Windows download package has been split into a driver package and an Intel PROSet package. The driver package must be installed prior to installing the Intel PROSet package.

Installation of Intel PROSet is optional. Intel PROSet software includes Intel PROSet for Windows Device Manager, Intel PROSet Adapter Configuration Utility (Intel PROSet ACU) , and Intel PROSet for Windows PowerShell software.

What's New in This Release:

- Linux and FreeBSD support for the Intel Ethernet Network Adapter E810-2C-Q2
- QinQ support
- NVM Update using devlink: Kernel versions 5.10 and later are needed for full devlink support using NVMUpdate
- FreeBSD RDMA driver for Intel Ethernet Controller 800 Series devices
- The Microsoft Windows download package has been split into a driver package and a Intel PROSet package. You can still download the entire release all in one package.

Intel Ethernet 800 Series Fixed Issues:

- Linux Driver: When the XDP program is loaded in native mode, a system crash might occur.
- Linux Driver: On Intel Ethernet E810-2C-Q2, you may see errors when there are more than 128 queues per traffic class.
- Linux Driver: The rx_gro_dropped statistics was removed and is no longer accounted for in rx_dropped netstats.
- Linux Driver: Until the system is rebooted, you may see a loss of traffic following an NVM Update. Rebooting the system resumes traffic.
- Linux Driver: The Intel ice driver interrupt moderation mechanism now utilizes the kernel DIMLIB library. This change has shown improvement across many workloads including large packet latency and UDP streams. Note that the ice driver from Release 25.6 (and earlier) does not have this change.
- Linux Driver: Unified Ethtool Statistics was added to Linux driver starting from Release 25.5.
- Windows Driver: On some platforms, an Intel Ethernet E810 OCP-based device might not retain link when the platform is powered down. The device regains link when the platform is powered up. Sending a Magic Packet to such a device does not wake the system.
- Windows Driver: Under heavy stress on Windows Server 2019, customers might see Event 260: "Failed to move RSS queue from VMQ.." in the system event viewer. This is due to the driver not moving a particular queue in time for it to move to a new CPU. This is a non-fatal message and traffic is still processed as expected.
- Linux RDMA Driver: In RoCEv2 mode, running the perftest ib_send_bw benchmark application with high QP count, rdma_cm, and the duration option might occasionally result in a Destroy QP Cmd Error and a device reset.
- NVM Update Tool: In ESXi, the device serial number appears as N/A.
- NVM: A workaround was added to prevent Errata "Device Fails to Initialize PCIe Link After Reboot".
- FreeBSD Driver: The FreeBSD ICE driver might show the wrong media type (25GBASE-AOC) for 25G-LR/SR optics when the advertise_speed parameter is set to 164 (1G+10G+25G).

This download is valid for the products listed below:

About Network Adapter Drivers:

When connected, the operating system usually installs a generic driver that helps the computer to recognize the newly attached device.

However, proper software must be applied if you want to make use of all features that the network adapter has available. This task also allows computers to properly recognize all device characteristics such as manufacturer, chipset, technology, and others.

Updating the adapter's drivers and utilities version might improve overall performance and stability, increase transfer speeds, fix different compatibility problems and several network-related errors, as well as bring various other changes.

To install this release, simply get the package, extract it if necessary, run the setup, and follow the instructions displayed on-screen. When done, don't forget to perform a system restart and reconnect the network adapter to make sure that all changes take effect properly.

Without further ado, if you intend to apply this version, click the download button and install the package. Moreover, check with our website as often as possible so that you don't miss a single new release.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
