Mellanox MCX516A-CCAT PCI Card Firmware 16.23.1020

Changes:

- RoCE DC: Added support for Dynamically Connected Transport (DC) in RoCE in ConnectX-5 adapter cards.
- Mini-CQE Compression: Enabled Rx mini-CQE compressed format for striding RQ.
- TX Steering Rules: Enabled TX steering rule on the application meta-data from the WQE. This functionality implements meta-data Reg A steering and meta-data Reg A and Reg B rewriting.
- Tunneling Offload/steering Match Criteria: Added MPLS over UDP and MPLS over GRE protocols for tunneling offload/steering match criteria.
- InfiniBand: Added support for IPoIB non-default Partition Keys (PKeys). Now the PKey values can be modified in the PKey table without the need of recreating the IPoIB (underlay) QPs.
- SR-IOV in Multi-Host/Socket-Direct: [Beta] Added support for SR-IOV in Multi-Host/Socket-Direct.
- Virtualization: Reduced firmware’s memory consumption to increase the supported number of VFs per PF to up to 100.
- Tools/Driver Version: Added support for QUERY_DRIVER_VERSION command. This command allows the PF driver to query its VFs driver version which was set by the SET_DRIVER_VERSION command.
- Resiliency: Shutting Down RDMA QPs with Excessive Retransmissions is a mechanism used to detect excessive retransmissions for an RC connection, and to close the connection in response to it. If the number of retransmissions due to a Local Ack Timeout, NAK-Sequence Error, or Implied NAK, during a specified period, exceeds the specified threshold, the QP will be handled as if the IB spec defined Retry Count was exceeded.
- Diagnostic Counters: Added new diagnostic counters to evaluate the number of ICMC hits and misses for particular resources.

Bug Fixes:

- Closed the vport as part of the fast teardown flow, to prevent Ack to be sent without been scatter to memory.
- Fixed an issue that occasionally caused the link to drop after running the 'reboot' command due to I2C being stuck.
- Fixed an issue that caused the tx_pause_storm_warning_events and the tx_pause_storm_error_events counters to increase even when there was TX pause.
- Fixed an issue related to the QoSConfig MADs that occasionally caused the firmware to issue an assert under certain device configurations.
- Fixed an issue where on high loaded Power9 systems with On-Demand-Paging (ODP) enabled, QP might have entered an error state in case the retry counter was exceeded during page fault recovery. As a result, if the page was fetched after QP has already been closed, page_- fault_resume error message would appear.
- Fixed an issue that resulted in a wrong sensor state report when running the PLDM sensor reading command and when a negative temperature was set with the hook.
- Fixed a speed issue for link mode Speed25GBaseSR.
- Pause duration: Physical port counters count in 512bits quantas, instead of microseconds.

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.
