Download Download NVIDIA Mellanox MCX653106A-ECAT SmartNIC Firmware 20.27.6008 for OS Independent Free

The firmware added during manufacture is used to run user programs on the device and can be considered as software that allows the hardware to run. Embedded firmware is used to control the functions of various hardware devices and systems, just as the operating system (OS) of a computer controls the functions of software applications. The firmware can be written to read-only memory (ROM), erasable programmable read-only memory (EPROM), or flash memory.

Important notes:

-Security reinforcement enhancement: This version contains important reliability improvements and security reinforcement enhancements. Mellanox recommends upgrading your device firmware to this version to improve the device’s firmware security and reliability.
-When upgrading or changing the configuration on a multi-host adapter card, for the changes to take effect, PCIe restarts must be sent from both hosts (servers) at the same time.
-SR-IOV-Virtual function (VF) per port-The maximum virtual function (VF) per port is 127.
-For functions that require a large amount of PCIe resources, it is recommended to enable the BIOS setting of “Decoding above 4G”. Such functions include: SR-IOV with a large number of VFs, PCIe emulation switches, and large BAR requests.

Changes and new features:

-Enable KP4RS FEC on the active fiber optic cable (OPN: MFS1S00-V0xxE).
-Disable PLR ​​on active fiber optic cables.
-Added support for FDR protocol.
-SHARP SAT is at GA level.
-Enable real-time update of end-to-end (E2E) credit data packages.

Bug fix:

-The CWDM4 AOM cable is not currently supported.
-When using the Cisco BiDi module at 100GbE link speed, the link between the ConnectX-6 adapter card and the Spectrum-2 SN3700 switching system will not be established.
-Sometimes, when working in split 2 X 100 mode with fiber optic cable, the link will not rise.
-Fixed an issue that prevented the correct PCIe Tx parameters from loading when changing the speed after disabling the PCIe link.
-Fixed an issue that prevented the desched_threshold field from working properly.
-Fixed an issue that caused the “roce_adp_retrans” counter to display the “local_ack_timeout_err” counter value.
-If loose sorting is disabled by running the “setpci” command, it will not work even if it is re-enabled by running the “setpci” command again.
-Update the BECN value of RoCE Tx CNP to 1.
-Align user memory pages to 2. For example, users should use 8k alignment (such as 0, 8k, 16k, etc., instead of 0, 4k, 12k, etc.).
-NRZ and PAM4 limitations in 100GbE adapter cards.
-The default configuration is NRZ speed in Auto-Neg mode
-PAM4 speed should be set manually (using MFT tool – mlxlink)
-PAM4 speed should be configured as a single speed: 50G_1x or 100G_2x
-200G_4x optical cable (including 200G_4x splitter cable) will only increase the link after manually configuring the PAM4 speed (50G_1x or 100G_2x)
-NRZ and PAM4 limitations in 200GbE adapter cards.
-The default configuration in Force mode is 200G_x4
-NRZ speed should be set manually. Configuration can include multiple NRZ speeds (using MFT tool – mlxlink)
-PAM4 speed should be configured as a single speed: 50G_1x or 100G_2x or 200G_4x
-In Ethernet mode, at 25/50/100GbE speed, only RS-FEC in mandatory mode is supported. Other user configurations are overwritten.
-Fixed the issue that caused the adapter card to get stuck in the “polling” state after resetting/restarting the card.
-Fixed PCIe PLL varactor calibration logic to account for potential silicon changes.
-Fixed an issue that caused the ZTR counter query to always return 0.
-Fixed an issue that caused the adapter card to fail to enter bypass mode when BMC disabled hardware arbitration.
-Fixed an issue where error report messages were discarded due to the “error report” filter not working properly.
-Fixed the redundant page consumption in init_hca.
-When using an HDR100 link with a cable length of 10m-30m, throughput may decrease.
-The sw_reset option is not supported when ATS is enabled.
-Fixed the ATS function problem.
-Since the string DB is not updated after Live-Patch, the tracker cannot run after Live-Patch.
-Fixed a rare issue that caused other active functions to receive malformed CQE during driver (PF or VF) uninstallation or FLR streaming.
-Fixed the problem that the PCI link cannot be established when the firmware is damaged.
-Fixed an issue that triggered FW assertion when Packet Pacing was enabled and QP was destroyed and caused the wrong release of resources.
-There are configuration restrictions when using the ConnectX-6 VPI card. One port is set to EN mode and the other port is set to IB mode.
-Fixed the issue that caused the firmware to hang when FLR occurred during disassembly. As a result, the disassembly process acquired a lock and never released it because it was aborted by the FLR.
-Fixed the performance issue that occurred when CAPI was enabled in NVConfig.
-When using Multi-GVMI and SR-IOV and a large number of virtual functions and sub-functions, the driver startup may fail for VF/sub-functions.
-Fixed an issue that slowed down the firmware process when executing many destroy XRQ commands on XRQ that supports DC transmission services.
-When the temperature changes, the HDR link may be interrupted due to a temperature change higher than 6 degrees Celsius.
-Fixed a rare issue that caused the firmware to get stuck in the following message in dmesg during driver restart or driver restart, and under QP timeout pressure (packet loss/network congestion): mlx5_core 0000:a1:00.0 : Firmware over 120000 MS in pre-initialized state, aborted.
-When connecting to an HDR switch at HDR speed, the bandwidth of the MFS1S00-H050E cable is 99G/s, and the bandwidth of the MFS1S00-H100E cable is 67Gb/s.
-In rare cases, when the firmware merge host stuck event occurs, the asynchronous event may be delayed in reporting and will not trigger until the next PCIe hangs on one of the hosts.
-Renamed GMP Mellanox vendor specific external capability mask enumeration from IsDiagnosticCountersSupported to IsDiagnosticDataSupported.
-The HDR link time when using optical and copper cables may take 6 minutes or more (up to 20 minutes).
-One port may hang while link maintenance is running, and the link of the second port may be switched.
-Fixed an issue where the firmware could not reset the port speed to its default speed HDR due to an error state in the firmware caused by the TEARDOWN_HCA and open source event. This event caused the properties in the firmware to not be reset to the default value between the drivers.
-Link jitter and packet loss during high/low temperature changes.
-When using a copper splitter cable up to 2m in HDR100 mode, the flow rate may drop.
-In rare cases, the HDR link may not be able to improve normally due to temperature changes.
-In the rare case that the driver executes the “2err” command and the QP is in the SQ exhausted state, the firmware may issue a WQ damage event instead of sending an error CQE on all WQEs.
-Fixed an issue that prevented users with non-port owner permissions from using the read DCBX to access the registry key REGID_DCBX_APP/REGID_DCBX_PARAM.
-When using an HDR cable to connect to a Switch-IB or Switch-IB 2 based switching system, the link may get stuck during polling.
-Fixed the problem of disordered data packet transmission due to internal detour competition.
-Fixed a rare issue that caused QP to incorrectly transition to an error state due to the invalidation of the memory key due to processing repeated read/atomic requests.

About the network adapter driver:

After connecting, the operating system usually installs a universal driver to help the computer recognize the newly connected device.

However, if you want to take advantage of all the functions available with the network adapter, 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 driver and utility version may improve overall performance and stability, increase transmission speed, fix different compatibility issues and some network-related errors, and bring various other changes.

To install this version, simply obtain the package, unzip it if necessary, run the installer, and follow the instructions displayed on the screen. When you are done, don’t forget to perform a system restart and reconnect the network adapter to ensure that all changes take effect correctly.

Without further ado, if you plan to apply this version, please click the download button and install the package. In addition, please visit our website as much as possible, so as not to miss any new version.
