Download Download NVIDIA MCX623102AC-GDAT SmartNIC Firmware 22.37.1014 for OS Independent Free

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

Important Notes:

– SR-IOV – Virtual Functions (VFs) per port – The maximum virtual functions (VFs) per port is 127.
– For features that require a lot of PCIe resources, it is recommended to enable the “4G+ decoding” BIOS setting. These features include: SR-IOV with a large number of VFs, PCIe emulated switches, and large BAR requests.
– Security Hardening Enhancements: This release contains important reliability improvements and security hardening enhancements. NVIDIA recommends upgrading device firmware to this version to improve device firmware security and reliability.

Changes and new features:

– Added coalescable buffer support (VIRTIO_NET_F_MRG_RXBUF in virtio spec) for VDPA kernel mode to improve performance for large MTUs (eg 9K). This feature is disabled by default and must be manually enabled when creating or modifying a virtio device. Note: For best performance, it is not recommended to enable this feature if the VDPA MTU is set to the default value (1500).
– This new feature enables a virtual machine to track and limit the activity of its Vports. This is done using the new q_counters counter which aggregates other Vports from PF GVMI.
– Added a flow rule to offload multicast traffic by broadcasting it to the multiflow table in FDB.
– Enables smooth, static switching between PCC algorithms. Additionally, users can now switch between PCC algorithms while running traffic.
– Added support for 32 operations in header modification mode using bulk allocation.
– Software can explicitly set the SL of the RTT response packet instead of taking it from the SL of the RTT request packet. The RTT response packet SL can be set/queried via CONGESTION_CONTROL_HCA_NP_PARAMETER MAD.

Added support for running PCC firmware traces without saving and sending DB strings to tools with the following changes:
– Added new string section in user PCC image creation tool
– Add new PCC DB string to MTRC access register output
– As far as tools are concerned: added support for reading string.db using MTRC access registers

Bug fixes:

– Added a safety mechanism to prevent links from getting stuck when bad tuning results are received. In this case, the linking process restarts and the mechanism retries to establish the link.
– Improved rate limit token reassignment algorithm.
– Improved non-consumable bandwidth reallocation.
– Fixed an issue that caused NODNIC VF to fail to ping when VLAN stripping was enabled.
– Fixed vDPA application initialization failure due to virtual queue creation failure. This failure is accompanied by a “0x8f7a: Ring address translation failed” assertion, which indicates that QEMU is giving incorrect permissions to the virtual ring memory.
– After switching to Programmable Congestion Control mode, the CNP Receive, Process and Ignore counters in the hardware counters do not work.

About network adapter firmware:

Once connected, the operating system usually installs generic firmware that helps the computer recognize the newly connected device.

However, if you want to take advantage of all the features your network adapter has to offer, you must apply the appropriate software. This task also allows the computer to correctly identify all device characteristics such as manufacturer, chipset, technology, etc.

Updating the adapter’s firmware and utility versions may improve overall performance and stability, increase transfer speeds, fix various compatibility issues and some network-related bugs, and bring various other changes.

To install this release, simply grab the package, unpack it if necessary, run the installer, and follow the on-screen instructions. Don’t forget to reboot your system and reconnect your network adapters when you’re done to make sure all changes take effect properly.
