Intel Network Adapter Driver 27.0 for Server 2012

What's New in This Release:

 
- Microsoft Windows Server 2022 support for devices based on the following controllers: Intel Ethernet Controller X552 and Intel Ethernet Controller X553

Intel Ethernet 800 Series Fixed Issues:

- Linux: Linux ice driver versions 1.4.x through 1.6.x have a performance regression that affects NVMe over Fabric baseline TCP performance using interrupt mode. This issue impacts interrupt mode workloads only; there is no impact to workloads using busy poll mode, such as ADQ. Fixed in ice 1.7.x and above.
- Linux: When changing the RSS queue value in VM while Double VLAN is configured, rx_vlano [rx-vlanoffload] may stop incrementing correctly.
- Linux: For configurations in which a VF is attached to a VM, avoid setting the MTU value of the VF within the range of 9199-9202. When the MTU is set to one of these values the VM may experience a memory leak leading to kernel panic when TCP traffic is running from a link partner to the VF.
- Linux: Rapid unloading and loading of the irdma and ice drivers may cause a kernel panic.
- Linux: There was a statistics issue where ifconfig/ip -s link show could potentially show overall statistics counting backwards due to a timing issue in stats collection. Ethtool -S statistics were unaffected by this issue and would show correct counts. This issue is fixed in ice driver 1.7.x and above.
- Linux: Packets received during the driver load are displayed as dropped because the packet drop counter was started before the driver was fully loaded. This was a cosmetic issue with no functional impact other than an increase in the dropped packets count. This issue is fixed in 1.7.x and above
- Linux: On CentOS 7.2, ethtool may report Speed as Unknown and you may see warnings in dmesg log. This does not affect traffic or device functionality.
- Linux: QoS bandwidth shaping and priority tagging may not be functional in CentOS 7.2.
- Linux: When double VLAN or Queue in Queue feature is enabled, the inner most traffic source might need to be limited to an MTU size of 1496 or less to avoid connection issues.
- Linux: When using Double VLAN configuration with a specific non-Intel link partner, TCP traffic might fail to pass through the inner VLAN interface when the MTU of this interface matches the MTU of the outer VLAN interface. Workaround: change MTU of inner VLAN to be 4 bytes less than the MTU of the outer VLAN.
- Linux RDMA: RDMA stability at application close is improved with NVM version 3.1+.
- Linux RDMA: Prior to the combination of ice 1.7.16/irdma 1.7.72/NVM 3.1 from Release 26.8, PFC for RDMA traffic was only functional on TC0. With NVMs and drivers (ice-1.7.16 and irdma-1.7.72) from the current Release 26.8, RDMA traffic can be configured for PFC on TCs other than TC0
- Linux RDMA: There might be a PSoD appearing during PF-reset when the NVMe to RDMA connection is active.
- Linux RDMA: 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 RDMA: After a system reboot, an Intel Ethernet Network Adapter E810 RDMA device in RoCEv2 mode might occasionally become active with a missing or incorrect GID. To correct the GID value, unload and reload the irdma driver.
- Firmware: FW treated SFI C2C as type SFF PHY, which caused a BMC link down.
- Firmware: When the admin queue command was executed to get the PHY recovery clock (0x0631), it was missing the Port number in the AQC.
- Firmware: The interface type was displayed as twisted pair instead of optical fiber.
- Firmware: Fixed an issue on the Intel Ethernet Network Adapter XXVDA4T where external PHYs do not report temperature correctly.
- Firmware: The PackageID0 SDP0 and PackageID1 SDP1 no longer have wrong assignments to the SDP PINs.
- Firmware: The NC-SI OEM command (0x4B) no longer fails.
- Firmware: Fixed an issue when the FW has not been properly mapped from the physical port to logical to get interface sensors.
- Firmware: Fixed an issue when the FW tries to read the PHY threshold even when the module does not that sensor.
- Firmware: Fixed an issue where the FW was trying to get power consumer parameters on a module that was not present.
- Firmware: Fixed an issue where the FW was handling GPIO interrupts before the board initialization was complete.
- Firmware: Fixed an issue where the FW PLDM command GetFirmwareParameters contains additional null characters.
- Firmware: Fixed an issue where the FW was reporting a module power value of module from an incorrect location.
- Firmware: FW maps the wrong cage index to logical port 0. As a result, customers may see the link API get an incorrect indication for the cage index related to logical port 0.
- Firmware: For PLDM Type 2 the device reports the port thermal sensor PDR and status for all types of connectivity; even those without temp sensor (temperature and thresholds reported as zeros).
- Manageability: When bifurcation is enabled on the Chapman Beach adapter, both Intel Ethernet 800 Series Adapters set the NC-SI Package ID as “0”.
- ADQ: VXLAN stateless offloads (checksum, TSO) and TC filters directing traffic to a VXLAN interface are not supported with Linux v5.9 or later.
- ADQ: When using multiple Traffic Classes (TCs) for ADQ application traffic, adding ntuple rules to the first queue of TC2 or higher does not work as expected. The ethtool ntuple rule fails for the first queue. This does not affect ntuple rules on TC1.

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.
