NVIDIA Mellanox MCX653106A-HDA SmartNIC Firmware 20.26.1040

Changes and New Features:

- [Alpha] Added support for 200GbE link speed only when in Force mode (non-Auto-Negotiation).
- Added support for Link Down Reasoning.
- Added support to the Physical Layer Retransmission (PLR) functionality for HDR speed.
- Removed PLR from active cables longer than 30m.
- Added Address Translation Service (ATS) support for MKEY and UMEM.
- Added support for exposing the VPD on the VF.
- Added support for Hairpin Drop Counter.
- This is a containerized sandbox per user, to access PRM command securely by using General Object commands, UMEM and UCTX contexts. The allowed functionalities of this capability depend on the user permissions. The following functionalities are still managed by the Kernel: Resource cleaning, UCTX stamping, and Blocking the physical address and IRQ from these UCTX.
- Added support for reporting the supported affiliated and unaffiliated asynchronous events to DEVX users through the command interface.
- Added support for creating software managed steering tables in eSwitch/FDB.
- This release contains important reliability improvements and security hardening enhancements.

Bug Fixes:

- Upon temperature changes, HDR link can potentially go down due to a temperature change higher than 6 degrees Celsius.
- Fixed a rare issue that resulted in firmware getting stuck with the below message in dmesg during driver restart or driver reboot, and under stress of QP timeouts (packet drops/network congestion): mlx5_core 0000:a1:00.0: Firmware over 120000 MS in pre-initializing state, aborting.
- The bandwidth on MFS1S00-H050E cables is 99G/s and on MFS1S00-H100E cables is 67Gb/s when connecting at HDR speed to an HDR switch.
- On rare occasions, when firmware coalesce Host stuck events occur, a async event might be delayed to be reported, and not be triggered until the next time the PCIe hangs on one of the hosts.
- Renamed the GMP Mellanox Vendor Specific External Capability mask enum from IsDiagnosticCountersSupported to IsDiagnosticDataSupported.

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.

  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.
