Intel Network Adapter Driver (IT Administrators) 26.0

New Software Support:

- Aggregated receive error counters for the i40e driver.
- Aggregated receive error counters for the ixgbe driver.
- i40e FreeBSD driver — When the VLAN_HWFILTER flag is enabled on an interface and there aren't enough hardware resources available to filter all the configured VLANs, the driver disables hardware filtering and enables the operating system or other software to filter VLAN tags.

Intel Ethernet 700 Series Fixed Issues:

- PROSet: When an Intel Ethernet controller has connection and it's bounded to a virtual adapter the connection test results states "TCP/IP protocol not configured" instead of "Cannot run this test because the device is bound to a virtual NIC".
- PROSet: In the Adapter Information tab, Negotiated link speed text is truncated. Only first word is shown. It’s exists only when the German language is used.
- PROSet: Team setting discrepancy observed between DMIX and PROSet ACU. A different default value of the check time (in seconds) is being used.
- Linux Driver: With DCB enabled, when dynamically switching LLDP/DCBX from firmware to software ownership using ethtool --set-priv-flags ethX disable-fw-lldp on command, an issue results in dmesg error messages and incorrect DCB configuration. Possible Workarounds: 1. Reload the Linux driver and/or 2. Shut down and re-enable the switch port connected to the affected adapter port.
- Linux Driver: Using all queues to create Traffic Classes (TCs) via the Application Device Queues (ADQs) feature might cause loss of network connection.
- Linux Driver: ip_link_spoof option is not available when using the SR-IOV Hypervisor management interface (VF-d).
- Linux Driver: For the XDP redirect feature, when using the ethtool -L combined [N] option, traffic being received on the Tx side is almost half of the packets received on Rx. There is no corresponding packet drop happening when checking netstat.
- Linux Driver: For Precision Time Protocol (PTP), there is no synchronization when SMA1 (GPIO_4) is input for the 1PPS signal.
- Linux Driver: When VF is disabled via SR-IOV Hypervisor Management Interface (VF-d) it cannot be enabled again.
- Linux Driver: Running two VM’s with multiple VF's might cause a Reboot with a General Protection Fault if the driver is unloaded while VF's are running traffic.
- Linux Driver: Express Data Path — On the newest kernels, system hangs might be observed after the eBPF program loads.
- Linux Driver: Auto negotiation cannot be disabled on the Intel Ethernet Controller V710 for 5GBASE-T.
- Linux RDMA Driver: There is approximately a 25% chance that a system crashes during RDMA CM connection and simple ping-pong test (ucmatose) when the number of connections is greater than 16000.

Intel Ethernet 500 Series Fixed Issues:

- Fixed: On Kernel version 5.8.5 or higher call trace is observed during loading xdp_redirect or xdp_tx.
- Fixed: Inventory traffic can be lost on Intel Server System R2208WFQ with Intel Ethernet Network Connection OCP X527.
- PROSet: When an Intel Ethernet controller has connection and it's bounded to a virtual adapter the connection test results states "TCP/IP protocol not configured" instead of "Cannot run this test because the device is bound to a virtual NIC".
- PROSet: In the Adapter Information tab, Negotiated link speed text is truncated. Only first word is shown. It’s exists only when the German language is used.

Intel Ethernet 300 Series Fixed Issues:

- PROSet: When an Intel Ethernet controller has connection and it's bounded to a virtual adapter the connection test results states "TCP/IP protocol not configured" instead of "Cannot run this test because the device is bound to a virtual NIC".
- PROSet: In the Adapter Information tab, Negotiated link speed text is truncated. Only first word is shown. It’s exists only when the German language is used.

About Ethernet Drivers:

Windows platforms generally apply a generic driver that allows motherboards to recognize the Ethernet component.

However, in order to make use of all network card (adapter) features, you must install a proper LAN driver that enables the hardware. This task enables systems to connect to a network, as well as collect all component characteristics such as manufacturer and chipset.

If you intend to update the driver version, know that this process can add support for new OSes, fix different compatibility problems, resolve related errors encountered during the product's lifetime, as well as include various other changes.

When it comes to the actual installation procedure, we should note that most producers try to make it as easy as possible, so following the steps should be a breeze: just get the downloadable package, run the setup, and follow the on-screen instructions.

There is a chance that other OSes could also be suitable, but it is not advisable that you install this release on platforms other than the specified ones. Remember to perform a system reboot once done, to allow all changes to take effect properly.

Therefore, if you wish to apply this version, click on the download button and enable your network card. To stay up to speed with the latest updates, check back with our website as often as possible.
