NVIDIA MCX750500B-0D00 SmartNIC Firmware 28.36.1010

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.

The ConnectX-7 smart host channel adapter (HCA), featuring the NVIDIA Quantum-2 InfiniBand architecture, provides the highest networking performance available to take on the world’s most challenging workloads. ConnectX-7 provides ultra-low latency, 400Gb/s throughput, and innovative NVIDIA In-Network Computing acceleration engines to provide additional acceleration to deliver the scalability and feature-rich technology needed for supercomputers, artificial intelligence, and hyperscale cloud data centers.

Changes and New Features:

- IB/Ethernet (IB NDR / 200GbE) supported ConnectX-7 adapter cards now raise at their default link protocol. For the list of these cards, please refer to the "Supported Devices" section of this Release Notes, see the cards that have (default mode) in their description. 
- Enabled provisioning of the OEM public key that is used for OEM NVconfig file signature verification.

Bug Fixes:

- Fixed an issue that caused the Downstream Port Containment (DPC) not to be exposed on the downstream ports of the top level PCIe switch in products supporting PCIe switch.
- Fixed an issue that resulted in PRBS lock loss (PRBS_CHK_ERR_CNT_NO_CLR field is raising) when the PRBS mode was first configured on the ConnectX-7 adapter card and then on the Wedge400 switch.
- Fixed an issue that caused wqe_based_steering CQEs not to be generated upon an error.
- Aligned RDE behavior to DSP0266 v1.15.0 table 23.
- Fixed a rare issue that resulted in link not raising when connecting a ConnentX-7 adapter card to IXIA in PAM4 speeds.
- Fixed an issue that resulted in device link down, and the device not being able to get traffic, when moving between two states DETECT and POLLING CONFIG in RTL.
- When connecting a ConnectX-7 adapter card to a ConnectX-5 or an NVIDIA Spectrum switch, configuring first 10G/40G and then configuring back 100G we result in linkup failure.
- When connecting with MMS4X00-NL400 transceiver at 200Gb/s, instability may be experienced upon link up. 
- When connecting a ConnectX-7 adapter card to ConnectX-7 adapter card and one side is configured to RM Loopback, and the port is toggled, link flap maybe experienced. 
- Live migration of MPV affiliated function pair is not supported when port numbers are changed. Each function should stay on the same port number as before migration.
- When decapsulation on a packet occurs, the FCS indication is not calculated correctly.
- SPDM Get Measurements might return an invalid signature while executed without the included measurements (request param2 = 0).
- The SPDM challenge command returns the hash of all the measurements without their headers.
- Connecting an HDR device to an NDR device with Optical cables longer than 30m causes degradation in the bandwidth.
- Enabled constant clock offset (visible using PPS out) when synchronizing the device using PTP in 25G or 10G port link speed.
- Fixed an issue that caused the Pkey table not to be updated, and wrong value to be sent, when the MADs handled in a long process were sent using GLOBAL_GVMI instead of vport0_gvmi.
- Fixed a wrong lane mapping to serdes when selecting the OSFP port and using only 4 lanes.

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 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.
