NVIDIA MCX755206AS-NEAT-N SmartNIC Firmware 28.35.3006-LTS

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.

The ConnectX-7 smart host channel adapter (HCA), featuring the NVIDIA Quantum-2 InfiniBand architecture, provides the highest networking performance available to take on the world’s most challenging workloads. ConnectX-7 provides ultra-low latency, 400Gb/s throughput, and innovative NVIDIA In-Network Computing acceleration engines to provide additional acceleration to deliver the scalability and feature-rich technology needed for supercomputers, artificial intelligence, and hyperscale cloud data centers.

Bug Fixes:

- Enabled ACS for single port cards.
- Added a new condition to check the port split number to resolve an issue that caused the port LEDs to be OFF.
- Fixed the NEGOTIATE_ALGORITHMS response according to the SPDM specification.
- Fixed an issue that caused the system not to detect the PCIe device during slot DC power cycle tests.
- Fixed an issue that caused the virtio-blk traffic to get stuck when working on vDPA over VFE mode.
- Fixed an issues that occurred during secure firmware update when decrypting and authenticating each chunk of data using its authentication tag. The issue appeared when the main code chunk was split between the user chunks and any GCM operation (e.g., flash read with decryption). This GCM operation broke the GCM context for main chunk authentication and therefore failed.
- Fixed an issue that resulted in the interface type being shown as "unsupported" in CMIS modules.
- Fixed an issue that prevent the ConnectX-7 OCP 3.0 card from detecting that the PCIe link was down during slot AC power cycle.
- Fixed an issue that resulted in device link down, and the device not being able to get traffic when moving between two states DETECT and POLLING CONFIG in RTL.
- Added the option to clear the DPC registers after warm reboot.
- Fixed wrong credits configuration when MAX_ACC_OUT_READ was configured.
- Fixed a rare issue that prevented the hardware from handling an error flow that occurred when accessing the DPA cluster L2 cache from the firmware processor. In this case the firmware processor hardware requested a VA=>PA translation from the internal mmio, and the address translation was broken by the mmio on the 4K page boundary.

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.
