Intel Ethernet 810 Series Fixed Issues:

- General: Due to the previous bugs in PF-to-port mapping in both NVM and UEFI Driver, old NVMs are not compatible with the new UEFI driver. As it pertains to HII, NVMs can still be updated via FMP.
- General: When a VF interface is set as 'up' and assigned to a namespace, and the namespace is then deleted, the dmesg log may show the error Failed to set LAN Tx queue context, error: ICE_ERR_PARAM followed by error codes from the ice and iavf drivers.
- LinuxDriver: Repeatedly assigning a VF interface to a network namespace then deleting that namespace might result in an unexpected error message and might possibly result in a call trace on the host system.
- LinuxDriver: When the queue settings of a port are modified using the ethtool -L ethx combined XX command, the Interrupt Moderation settings reset to default.
- LinuxDriver: When the maximum allowed number of VLAN filters are created on a trusted VF, and the VF is then set to untrusted and the VM is rebooted, the iavf driver may not load correctly in the VM and may show errors in the VM dmesg log.
- LinuxDriver: If trusted mode is enabled for a VF while promiscuous mode is disabled and multicast promiscuous mode is enabled, unicast packets may be visible on the VF and multicast packets may not be visible on the VF. Alternatively, if promiscuous mode is enabled and multicast promiscuous mode is disabled, then both unicast and multicast packets may not be visible on the VF interface.
- LinuxDriver: A VF may incorrectly receive additional packets when trusted mode is disabled but promiscuous mode is enabled.
- LinuxDriver: Receive hashing might not be enabled by default on Virtual Functions when using an older iavf driver in combination with a newer PF driver version.
- LinuxDriver: Linux sysctl commands, or any automated scripting that alerts or sets /proc/sys/ attributes using sysctl, might encounter a system crash that includes irdma_net_event in the dmesg stack trace. Workaround: With OOT irdma-1.8.X installed on the system, avoid running sysctl while drivers are being loaded or unloaded.
- LinuxDriver: irdma stops working if the number of ice driver queues are changed (ethtool -L) while the irdma driver is loaded. As a workaround, remove (if previously loaded) and reload irdma after changing the number of queues.
- Firmware: When sending an AQC to start, the LLDP agent does not change the property NetworkAdapter.LldpEnabled to True.
- Firmware: Flow control settings have no effect on traffic, and counters do not increment with flow control set to TX=ON and Rx=OFF. However, flow control works fine with values set to TX=On RX=ON.
- FreeBSDDriver: Due to changes in the reset path, several errors are seen in dmesg when trying to re-establish link after an nvmupdate. This does not effect functionality, as nvmupdate requires a reboot to be complete.

Intel Ethernet 700 Series Fixed Issues:

- Linux driver: VLAN tagged traffic sent from other VFs attached to NIC can be seen on other VFs. This is due to issue with NIC settings and offload settings of VFs. As a workaround, disable TX VLAN offload on VFs: ethtool -K <ethX> tx-vlan-offload off. This does not affect egress traffic from outside of the NIC.
- EFI Driver: In the BIOS Controller Name as part of the Controller Handle section, a device path appears instead of an Intel adapter branding name.

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.
