Mellanox MCX455A-FCAT VPI Card Firmware 12.18.1000 Description

Changes and New Features:

- RX Loss (BaseT link down indication): Added logical link indication in SFP to BaseT modules and disabled logical link when peer port is down.
- SFP Rate: Added support for 10GbE in 25GbE SFP optical modules
- PDDR: Enables mlxlink tool to collect data on the PHY link status and provides link down reasons and additional link related information.
- KR Tx Response: Enabled TX configuration response and movement during Link Training in Ethernet.
- Phy Test mode: Added support at lane rate of 12.89Gb.
- Head of Queue (HoQ) per TC: Limits the amount of time a packet may head a Traffic Class (TC) transmission queue, without being transmitted. Stale packets are discarded. Active by default for TCs adhering to link level flow control
- User Access Region (UAR) 4KB Granularity Allocation: UAR page size currently is set to 4KB and not according to what the system page size determines.
- No Driver NIC (NODNIC) Performance Improvement: Improved performance of Doorbell from User Access Region (UAR) and Clear interrupt from User Access Region (UAR
- Counters: Added support for additional transport counters.
- On Demand Paging (ODP) DC: Added ODP support for DC.
- Scatter to CQE on Sender for DC: Enabled scatter-to-CQE for sent packets for DC.
- CQ modify: Enabled moderation period modification in CQ modify command.
- VMQ Rate limit per function: [Beta] Added support for minimum/maximum rate limit per vport in SR-IOV.
- Network traffic between UEFI-Shell and OS: Enabled network traffic between UEFI-Shell and OS.
- non-RDMA capable VFs: Enabled the PF to force disable RoCE for its VFs.
- PRM Access Registers Added 2 new access registers: Management Capabilities Mask Register and Ports CApabilities Mask Register Fields. For further information, please refer to the PRM.
- Loopback Enabled/Disabled: Enabled VNIC the control to enable/disable its local loopback traffic.
- RDMA RX Flow Table: Added the option to open a receive RDMA Flow Table and to forward RoCE traffic to some destination QP.

Bug Fixes:

- Fixed an issue which caused the HCA mad response to contain the incoming packet Pkey and not the matched Pkey.
- Modified PCIe Tx configuration.
- Fixed an issue that prevented the software to set ECN parameters (min_rate, max_rate, rate_to_set_on_first_cnp) to values >32768.
- Fixed an issue which caused the link speed to raise as DDR when connected with certain copper cables to devices supporting up to QDR speed.
- Fixed an issue which prevented physical counters from reseting. Now the physical counters are reset on first driver start.
- Fixed possible negotiation issues with 3rd parties.
- Fixed a rare issue which caused FDR/56GbE link to raise with errors.
- Fixed an issue which caused scheduling_context.element_type to be taken into consideration with performing verifications, when running the modify_scheduling_context command, although the field is reserved.
- Fixed an issue which caused the eSwitch max_average_bw ref counter to decrement in TEARDOWN_HCA/ FLR VF regardless of the max_average_bw value set, although the ref counter design was to increment on every max_average_bw != 0 (limited).

About Network Adapter:

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.
