NVIDIA Mellanox MCX515A-CCAT SmartNIC Firmware 16.20.1010

Changes and New Features:

- [Beta] Performance and stability improvements.
- [Alpha] Added support for Tag Matching DC (RNDV/EAGER traffic)
- Added support for send/receive Out-of-Order RDMA packets required by the Adaptive Routing. Adaptive Routing (AR) enables the switch to select the output port based on the port's load.
- Added trust level for QoS prioritization according to the DSCP or PCP.
- [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.
- [InfiniBand only] Changed the Multi-Host/Socket Direct routing to be LID based instead of GID based. Thus, GRH/GID index is not required.
- [Beta] Added support for relaxed ordering write in memory keys.
- Enhanced RDMA counter
- Added 2 new per Host TLVs
- Modifies the packets header.
- Enables fast unloading driver by using Teardown HCA with op_mode=1 (panic mode).
- Added support for enhanced IPoIB (QP.ulp == 2) in virtualized system (SR-IOV / Multi-Host / Socket Direct)
- Added support for SFP power class.
- 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 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 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.
- Setting more than 8K QPs with hca_sq_owner == 1 connected to an RNDV XRQ is currently not supported. 
- Fixed performance issues to improve Packet Pacing performance.
- Fixed an issue causing physical errors observed on Ixia 100GbE receiver
- Fixed an issue that caused the ipoib_enhanced_offloads indication (in the HCA capabilities) to report 0 while SRIOV_EN=1.

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.
