NVIDIA MCX75510AAS-HEAT SmartNIC Firmware 28.34.1002

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.

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:

- Enabled MACsec full offload for NIC tables (aware mode). UnTil now full offload was available only for FDB tables.
- Added LLDPEnable, LLDPTransmit and LLDPReceive properties to the RDE Port schema implementation.
- Added support for PPCC register with bulk operations, MAD for algorithm configuration and tunable parameters.
- Optimized both of the DPA's infrastructure and algorithm to be Programmable CC based.
- Added support for programmable counters for PCC via PPCC register and MAD.

Bug Fixes:

- Added support for SPDM Get_measurements command. Note: Executing the command with a signature request without measurements, can cause an invalid L1 hash calculation.
- Added support for SPDM Challenge command.
- Fixed PCIe link down failures during PCIe speed change tests.
- Fixed an issue where set_flow_table_entry failed when aso_flow_meter action was used. 
- Enabled Multi-Host RX Rate-limiter configuration via the QEEC mlxreg and the max_shaper_rate field.
- Added "Command Unsupported" response code in cases when running the MCTP control command "Get Vendor Defined Messages Supported", and there were no supported VDMs.
- Added the following new checks to commands' interface: CREATE/MODIFY QP/DCT - blocking QP/DCT with adaptive routing (multi_path field) if gvmi has MKEY with Signature and CREATE_MKEY- blocking the signature option if gvmi has open QPs/DCTs with the adaptive_routing feature enabled
- Implemented a firmware flow to power up/down the PLL from downstream links upon PERST assertion/de-assertion.
- MAC allocation in adapter cards that support Port-Per-Host feature ("host isolation") is reordered to fit the required range. Note: After burning a new firmware, the user must power cycle the server, and run the DHCP flow to recover the MAC changes.
- On rare occasions, when connecting a ConnectX-7 adapter card to an NVIDIA Spectrum-3 switch system using the optical cable OPN MFA1A00-C003, the link up time is ~7sec.
- Fixed a race condition occured between the duplicate read and QP commands (2RST, 2ERR and Destroy) in the signature that caused the command to hang.
- Enabled sending and receiving traffic with a different LID than the host LID in MetroX applications.
- Enabled sending and receiving traffic with a different LID than the host LID in MetroX applications.
- The an_disable flow is not supported in ConnectX-7 adapter cards for 25GbE and 50G_2x link speeds when using one of the following cables: MT1841VS00827 (rev A4) and MT1830VS00895 (rev A3). The flow is supported only when configuring FEC using the PPLM register.
- Host Chaining is currently not supported in ConnectX-7 adapter cards.
- Link flapping may occur when using ConnectX-7 adapter cards with HDR optic cables.
- Congestion Control is not enabled when one link type of different ports is different.
- A Bit Error Rate (BER) of 1e-9 might occur when using optical cables.
- Configuring 400G_8x in force mode is currently not supported.
- LRO is currently not supported.

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.
