Intel Ethernet 800 Series Fixed Issues:

- Linux Driver: Prior to irdma version 1.8.45, installing the OOT irdma driver on a system with RDMA-capable Intel Ethernet Connection X722/Intel Ethernet Network Adapter X722 ports and using an OS or kernel with an in-tree irdma driver could cause a system crash. To prevent a system crash when using OOT irdma drivers, either use irdma 1.8.45, or update i40e version (2.18.9 or greater) and load it before this new irdma is loaded.
- Linux Driver: AF_XDP based applications may cause system crash on packet receive with RHEL based 4.18 kernels.
- Linux Driver: During a long reboot cycle test (about 250-500 reboots) of the Intel Ethernet 800 Series adapters, the Intel ICE and iavf driver may experience kernel panics leading to an abnormal reboot of the server.
- Linux Driver: The commands ethtool -C [rx|tx]-frames are not supported by the iavf driver and will be ignored. Setting [tx|rx]-frames-irq using ethtool -C may not correctly save the intended setting and may reset the value back to the default value of 0.
- Linux Driver: Interrupt Moderation settings reset to default when the queue settings of a port are modified using the ethtool -L ethx combined XX command.
- Linux Driver: When a VM is running heavy traffic loads and is attached to a Virtual Switch with either SR-IOV enabled or VMQ offload enabled, repeatedly enabling and disabling the SR-IOV/VMQ setting on the vNIC in the VM may result in a BSOD. Linux RDMA Driver
- Linux Driver: In order to send or receive RDMA traffic, the network interface associated with the RDMA device must be up. If the network interface experiences a link down event (for example, a disconnected cable or ip link set down), the associated RDMA device is removed and no longer available to RDMA applications. When the network interface link is restored, the RDMA device is automatically re-added.
- Linux Driver: RHEL 8.5 only: Any usermode test that uses ibv_create_ah (For example, a RoCEv2 usermode test such as udaddy) will fail.
- Linux Driver: Due to a nondeterministic race condition, if the irdma driver is loaded in Linux by an Intel Ethernet 800 series device with non-standard MTU (i.e., non-1500B MTU), the system's network interfaces may fail to load after reboot. After failing to load, interactions with the networking stack may hang on the system. Multiple reboots may be required to avoid the condition.
- Linux Driver: The Devlink command devlink dev param show (DEVLINK_CMD_PARAM_GET) does not report MinSREV values for firmware (fw.mgmt.srev) and OROM (fw.undi.srev). This defect was also seen on the NVMUpdate tool, which caused an inventory error.
- Windows Driver: When a VM is running heavy traffic loads and is attached to a Virtual Switch with either SR-IOV enabled or VMQ offload enabled, repeatedly enabling and disabling the SR-IOV/VMQ setting on the vNIC in the VM, may result a VM freeze/hang.
- Linux RDMA Driver: iWARP mode requires a VLAN to be configured to fully enable PFC.
- Firmware: Following a firmware update and reboot/power cycle on the Intel Ethernet CQDA2 Adapter, Port 1 is displaying NO-CARRIER and is not functional.
- Firmware: Added a state machine to the thermal threshold activity so that when the switch page fails, it tries again from the same state.
- Firmware: FW not allow link if module not supported in lenient mode.
- Firmware: RDE Device is reporting a RevisionID property of PCIeFunctions schema as 0x00, instead 0x02.
- Firmware: The RDE device reports its status as Starting (with low power), even though it is in standby mode.
- Firmware: Wake On LAN flow is unexpectedly triggered by the E810 CQDA2 for OCP 3.0 adapter. The server unexpectedly wakes up automatically from S5 power state in few seconds after shut down from the OS, and it is impossible to shut down the server
- Firmware: Fixed an issue where the FW was reporting a module power value of module from an incorrect location.
- NVM: If the error message OS layer initialization failed is displayed, please update the Windows QV driver to the version included in this release. Note: If you are using Proset, an update of the QV driver may also require updating the Proset. 

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.

  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.
