NVIDIA MCX631102AE-ADA SmartNIC Firmware 26.35.1012

Firmware which is added at the time of manufacturing, is used to run user programs on the device and can be thought of as the software that allows hardware to run. Embedded firmware is used to control the functions of various hardware devices and systems, much like a computer’s operating system (OS) controls the function of software applications. Firmware may be written into read-only memory (ROM), erasable programmable read-only memory (EPROM) or flash memory.

Important Notes:

- SR-IOV - Virtual Functions (VF) per Port - The maximum Virtual Functions (VF) per port is 127.
- It is recommended to enable the “above 4G decoding” BIOS setting for features that require large amount of PCIe resources. Such features are: SR-IOV with numerous VFs, PCIe Emulated Switch, and Large BAR Requests.
- Security Hardening Enhancements: This release contains important reliability improvements and security hardening enhancements. NVIDIA recommends upgrading your devices' firmware to this release to improve the devices’ firmware security and reliability.

Changes and New Features:

- Added support for copy modify header steering action to/from the UDP field.
- Added resource dump segments: SEG_HW_STE_FULL that includes dump to STE and all its dependencies and SEG_FW_STE_FULL that include dump to FW_STE and to HW_STE_FULL in range
- As the software requires additional space before and after a packet is scattered for its processing for stridden RQ, the hardware will allocate the required room while scattering packets to spare a copy. 
- QoS priority trust default state can now be changed using the new nvconfig: QOS_TRUST_STATE_P1 and QOS_TRUST_STATE_P2. The values that can be used to set the default state are: TRUST_PORT, TRUST_PCP, TRUST_DSCP, and TRUST_DSCP_PCP

Bug Fixes:

- Fixed an issue that caused the patch to the RDE LLDPEnable property in Port schema not to be updated after the host reboot.
- Fixed an issue that caused RDE (Redfish) PATCH operation to LLDPTransmit properties "ManagementAddressIPv4", "ManagementAddressIPv6" and "ManagementAddressMAC" to be applied only in the first attempt but failed in the next.
- Fixed an issue that caused PLDM AEN event receiver media to be changed unexpectedly and destination BDF to be overridden with garbage when some PLDM packet were received from the SMBus layer.
- Fixed PCIe SKP OS generation interval for Gen1 and Gen2.

About Network Adapter Firmware:

When connected, the operating system usually installs a generic firmware 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 firmware 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.
