NVIDIA Mellanox MCX713106AC-VEAT SmartNIC Firmware 28.33.4030

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:
- 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:

- Cables: Added support for 100G & 200G optical cables (InfiniBand & Ethernet). Please note this support comes with a limitation when connecting ConnectX-7 to a ConnectX-6 Dx or an NVIDIA Spectrum-3 as described in Known Issues 3070409. 
- Firmware Based Attestation Flow: Attestation is a cryptographic reporting of the security configuration of a device, used by a platform to establish trust in the device. The device’s security configuration includes (but is not limited to) its identity, the code it is running and the states of security related mechanisms and assets. This new capability enables BMC to attest the device over SPDM protocol. The feature works for secure NICs with production certificates installed. SPDM protocol is defined in DMTF DSP0274 v1.1.0.

Currently the following SPDM commands are supported:

- GET_VERSION
- GET_CAPABILITIES
- NEGOTIATE_ALGORITHMS
- GET_DIGESTS
- GET_CERTIFICATE
- Since CHALLENGE and GET_MEASUREMENTS are not functional yet, when they are called, the NIC will respond with RESPONSE_NOT_READY.

Bug Fixes:

- On rare occasions, the HDR speed link up time when using the optical module MFA7U10-H010 might take up to 70sec.
- When connecting a ConnectX-7 adapter card to an NVIDIA Quantum switch using the copper cable (MCP1600-E01AE30), the link is Down when in EDR speed.
- Trying to query/burn the firmware using the flint utility when the image is pending (after firmware burn and before firmware reset), results in the action's failure.
- When changing the protocols from ETH to IB on two ConnectX-7 adapter cards connected to each other, the ports on both sides must be toggled to get the link up.
- Connecting a ConnectX-7 adapter card to either a ConnectX-5 adapter card or to an NVIDIA Spectrum switch system is supported only when using a 100GbE optic cables and when configuring ConnectX-5 or the NVIDIA Spectrum switch system to Force Mode.

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.

  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.
