NVIDIA MCX755106AC-HEA SmartNIC Firmware 28.43.1014

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) provides up to four ports of connectivity and 400Gb/s of throughput, hardware-accelerated networking, storage, security, and manageability services at data center scale for cloud, telecommunications, AI, and enterprise workloads. ConnectX-7 empowers agile and high-performance networking solutions with features such as Accelerated Switching and Packet Processing (ASAP2), advanced RoCE, GPUDirect Storage, and in-line hardware acceleration for Transport Layer Security (TLS), IP Security (IPsec), and MAC Security (MACsec) encryption and decryption. ConnectX-7 enables organizations to meet their current and future networking needs in both high-bandwidth and high-density environments.

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:

- Added support for PCIe Telemetry (NSM Type 2).
- Migrated PCC NP solution from ACE hardware platform to DPA hardware platform. The new capability is applicable to the following 2 modes: PCC_INT_EN=True and PCC_INT_NP_RTT_DATA_MODE=INGRESS_BYTE / PCC_INT_EN=True and PCC_INT_NP_RTT_DATA_MODE=NO_DATA. The first mode is used to support ZTRCC RX bytes in RTT response.
- Added the option to indicate an error CQE event on every selected function per eSwitch manager. This indication is defined as a new WQE including the relevant information about the error (such as: syndrome, function_id, timestamp, QPs num etc.). The feature is configured using a new general object: RDMA-Telemetry object, and depends on the following new caps: HCA_CAP.rdma_telemetry_notification_types and HCA_CAP.rdma_telemetry.
- Extended kernel lockdown permission set. The following sub-operations can now be called by tools (permission TOOLS_RESORCES) using new HCA capability bitmask field: tool_partial_cap.
The 5 sub-operations are:
- QUERY_HCA_CAP with other function
- QUERY_VUID with direct data
- QUERY_ROCE_ADDRESS with other vport
- SET_HCA_CAP with other function
- POSTPONE_CONNECTED_QP_TIMEOUT with other vport
The new added caps are:
- tool_partial_cap.postpone_conn_qp_timeout_other_vport,
- tool_partial_cap.set_hca_cap_other_func
- tool_partial_cap.query_roce_addr_other_vport
- tool_partial_cap.query_vuid_direct_data
- tool_partial_cap.query_hca_cap_other_func
- Added support for QoS scheduling across multiple E-Switches grouped in a LAG. VPort members of a Physical Function can be added to a rate group from another Physical Function and rate limits of the group will apply to those VPort members as well.
- Added 'table_type_valid' and 'table_type' fields to the steering action (STC) "Jump To Flow" table parameters to enable the user to jump from NIC_TX to FDB_TX and bypass the ACL table.
- Enabled hop reduction by bypassing NIC domain in various use cases. Such action r educes the number of hops (improves PPS) to deal with mass number of flows and devices. To enable this new capability, a new STC action type "JUMP_TO_FDB_RX" was added to allow jumping into the RX side of a table.
- Increased the maximum number of supported "ARC-IN" from 1 to 8 and "ARC-OUT" from 3 to 8 for the dynamic flex parser.
- [Alpha] Added support for PSP Crypto offload transport mode.
- Added histogram support for rate and Round-Trip Time (RTT) in PCC ZTR_RTTCC.
 

Bug Fixes:

- Added a recovery step in case of CQ doorbell getting lost during VF migration.
- PLDM includes port temperature sensor PDR only if an active cable is connected.
- Changed PCIe Geen4/5 new static configuration for VGA gain and CTLE.
- Fixed an issue that occasionally caused PTP accuracy degradation for port speed configured to 1G or 10G.
- Fixed an issue that resulted in MSIx reduction flow triggered with a wrong limitation (the total number of MSIx is reduced from 8k to 4k by mistake) when the dynamic MSIx feature is enabled and virtio emulation is disabled.
- Fixed lossless packet drops at 400GB 4 lanes when using an optic fiber cable.
- Fixed the query for FACTORY default NV configuration values. The firmware always returned the "next" value to be applied.
- Fixed an issue related to override TP4 settings.
- Changed the CTLE and VGA gain for Gen4/5 starting point.
- Increased SPDM's RDT value.
- Fixed a rare certificate signature verification error.
- Fixed an issue that caused issues during the cables' linkup process after reinserting a module in multi ASIC platforms.
- Fixed the user_cc_en default value (mlxreg).

About Wireless LAN Drivers:

Windows OSes usually apply a generic driver that allows systems to recognize the wireless component. However, in order to use all available features of this hardware, you must install the appropriate drivers.

Enabling the wireless card allows systems to read chipset information and manufacturer name, as well as connect to a network without using an Ethernet cable.

Updating the driver version can resolve different compatibility issues, fix related errors spotted throughout the product's usage, add support for new operating systems, improve transfer speed, as well as bring various other changes.

As for applying this release, the installation steps should not pose to much of a challenge since each producer intends to make the procedure as easy as possible: just download the package, run the setup, and follow the on-screen instructions.

Bear in mind that we do not recommend you install this release on OSes other than the specified ones even though other platforms might also be suitable. Also, when the update has finished, do perform a restart to ensure that all changes take effect properly.

Therefore, if you wish to apply this package, click the download button, and setup the wireless card on your system. Moreover, if you want to stay “updated one minute ago,” check with our website as often as possible.
