Intel PROSet/Network Adapter Driver 26.3 for Windows 8.1 64-bit

What's New in This Release:

- Support for Intel Ethernet Network Adapter E810-XXV-4 for OCP 3.0
- Base drivers for Intel Ethernet 800 Series devices now support health status messages to report abnormal NIC issues
- Added switchdev suppot
- Added support for higher power modules on select Intel Ethernet Network Adapters.

Intel Ethernet 800 Series Fixed Issues:

- General: In 8x10G mode link may not be established on some ports if the link is not connected at power on.
- Linux Driver: Ethtool was incorrectly reporting supported and advertised auto-negotiation settings. This has been fixed.
- Linux Driver: The driver is incorrectly flagging egressing packets which causes LLDP packets to be dropped from interfaces.
- Linux Driver: Driver rebuild may be failing due to vLAN add/delete failures. This has been fixed.
- Linux Driver: The call trace due to the use of WQ_MEM_RECLAIM flag has been fixed.
- Linux Driver: Unloading the ICE driver after a PCI reset causes an error in dmesg.
- Linux Driver: Server may perform reboot after adding VxLAN filter.
- Linux Driver: On an Intel Ethernet E810 2CQDA2 adapter in single VLAN mode, users might see packets with S-tag being dropped. This isn't seen with double VLAN.
- Windows Driver: VxLAN and RDMA stays active when Intel Ethernet Network Adapter E810 is in Safe Mode.
- Windows Driver: When updating from Release 25.6 to Release 26.1 using LANConf, the error "Shared flash write failed!" might be displayed at the end of the update. This does not indicate an update failure. Reboot the system to load the latest firmware.
- Linux RDMA Driver: If setting the device MTU to either 4096 or 2048, applications using RoCEv2 UD might hang. Workaround: Set the MTU values to 4097 instead of 4096 and 2049 instead of 2048.
- Linux RDMA Driver: RDMA vLAN may not be supported in the current release.
- NVM Update Tool: Reboot might fail after an update if the PRESERVATION entry has NONE or SELECTIVE in the confiuguration file. To workaround this issue, remove the entry and let the tool update using the default full preservation option.

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.
