Mellanox MCX455A-FCAT VPI Card Firmware 12.20.1010 Description

New Features:

- DSCP: Added trust level for QoS prioritization according to the DSCP or PCP.
- DSCP: [Beta] Added ingress buffer management for: ingress traffic mapping to a buffer according to priority and buffers sizes and lossless parameters
- Secured Firmware Updates: [Beta] Secure Firmware Updates provides devices with the ability to verify digital signatures of new firmware binaries, in order to ensure that only officially approved versions are installed on the devices.
- Multi-Host/Socket Direct Routing to be LID based: [InfiniBand only] Changed the Multi-Host/Socket Direct routing to be LID based instead of GID based. Thus, GRH/GID index is not required. Note: This feature requires SM 4.8.1 and above.
- Relaxed Ordering: [Beta] Added support for relaxed ordering write in memory keys.
- RDMA Counters: Enhanced RDMA counter
- TLV for PCI class code: Added 2 new per Host TLVs.
- Fast Teardown: Enables fast unloading driver by using Teardown HCA with op_mode=1 (panic mode).
- IPoIB Virtualization: Added support for enhanced IPoIB (QP.ulp == 2) in virtualized system (SR-IOV / Multi-Host / Socket Direct)
- SFP Power Flow Improvement (level 2,1): Added support for SFP power class.
- 10GBaseT module: Added support for 10GBaseT modules

Bug Fixes:

- Fixed a link issue on Intel 10GbE Optical module PN: R8H2F, Y3KJN.
- Fixed an issue that caused the link to raise as DDR instead of QDR after firmware reset when connected to switch 4036.
- Fixed an issue that caused the device to hang upon warm reboot.
- Fixed an issue that caused the TX traffic not to send packets when using VF index (ARI) bigger than 127.
- Fixed a scaling issue with more than 1k QPs for ECN by moving from per QP caching to per IP to allow better scale with number of host in the fabric.
- Enabled firmware resync of the internal clocks after getting out of the standby mode to prevent PTP time sync from getting out of sync after system warm-rebooted due to system getting into a low-power (standby) mode.
- When running RoCE over VRRP, enabled the device to receive RoCE packet with different source MAC than the original RoCE packet's destination MAC, to allow routing between different subnets.
- Fixed an issued that caused LLDP not to enable PFC configuration currently when DCBX transitioning flow control configurations was set from Global Pause to PFC.
- Fixed an issue that caused TX to get stuck when a link fail-over occurred in LAG and the firmware switched between the two ports. Additional credits reset flow were added when the firmware moved between different port,vl.
- Rephrased and improved external troubleshoot messages in PDDR register.
- Improved SR-IOV performance.
- The ipoib_enhanced_offloads indication in the HCA capabilities reports 0 while SRIOV_EN=1.
- Fixed an issue that prevented ibdump from functioning properly on Connect-X-4 second port.
- Fixed an issue on an ETH port with SR-IOV enabled that prevented packets from reaching the BMC (failure in steering loopback resolution) if the BMC addresses were configured after VF initialization, and the VF was trying to send traffic to the BMC (that located on the same phy port).
- Fixed an issue which caused the rate limiter not to function when setting a rate to tc 7.
- Fixed the PCIe TX glitch during Recovery.Speed state of the link training to PCIe Gen3.
- Fixed an issue related to the PortRcvDataVLExtended/PortXmitDataVLExtended parameter that caused the counters’ value to be reported in octets instead of dwrods.
- QP ULP modes 0 and 1 cannot be assigned to the same Multicast group.
- Fixed an issue in standby (WoL) modes only that caused the actual current consumption in 1.2V rail to be higher by<33mA than the advertised values although the total IC consumption is as advertised.
- Mapping an SL to VL 15 is currently not supported. Trying to do so, will cause a health buffer fatal internal error report.

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.
