NVIDIA MCX623105AS-VDA SmartNIC Firmware 22.38.1002

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 forwarding INT packets to the user application for monitoring purposes by matching the BTH acknowledge request bit (bth_a).
- Improved the IPsec CPS by using bulk allocation. For cases in which log_obj_range == 0, single IPSEC object will be allocated and initialized as before keeping backward compatibility. For better performance, it is recommended to work with IPsec bulk allocation and to initialize IPsec ASO context not via the firmware but via the hardware using ASO WQE.

Bug Fixes:

- Fixed a link failure that occurred due to a wrong 'is_inphi_cable' indication.
- Enabled "Link Maintenance" for 25G speed per lane to avoid a margin degradation due to a temperature drift.
- Fixed an issue in the steering definers used in LAG with IPv6 packets.
- Improved token calculation.
- Fixed a firmware assert that occurred when tried to verify if the module supported "swap".

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.
