NVIDIA Mellanox MCX654106A-ECA SmartNIC Firmware 20.35.1012

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:
- Security Hardening Enhancements: This release contains important reliability improvements and security hardening enhancements. Mellanox recommends upgrading your devices firmware to this release to improve the devices’ firmware security and reliability.
- When upgrading or changing the configuration on multi-host adapter cards, for the changes to take effect, PCIe restart must be simultaneously sent from both hosts (servers).
- 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.

Bug Fixes:

 
- Added support for copy modify header steering action to/from the UDP field.
- 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 the RXT E2E inflight to hang.
- RDMA partition is now reported only if NIC+RDMA mode is enabled.
- 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 a wrong address issue for XRQ Event Backend Controller Px Syndrome event in multi-host system during FLR.
- Fixed PCIe SKP OS generation interval for Gen1 and Gen2.
- Fixed an issue that prevented InfiniBand L2 QP from receiving RDMA traffic.
- Running with a debug firmware reduces security as if token was applied.

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 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.
