Mellanox MCX4421A-ACAN Network Card Firmware 14.22.1002 Description

Changes:

- Software Reset Flow enables the device to recover from fatal errors. The flow includes software detection of a fatal error, automatic creations of an mstdump file for future debug by the software, and resetting of the device. The feature is enabled using an mlxconfig command.
- Steering Discard Packet Counters: Any received packet which is dropped by the device is accounted for. To enable this functionality, the following counters were added to count the discard packets (per vport).
- Virtual Functions (VF): Increased the number of VFs that can work with full VMQoS (8 TC) per PFs as follow: in dual port devices to 20 VFs and in single port devices to 58 VFs
- Pause Frame Duration and XOFF Resend Time: Increased the Pause Frame Duration and the XOFF Resend Time to the maximum value defined by the specification.
- PCI Relax Ordering: mlxconfig configuration can now enable or disable forced PCI relaxed ordering in mkey_context. If this feature is enabled, the software per mkey configuration is ignored.
- vport Mirroring: Packets are mirrored based on certain mirroring policy. The policy is set using the “set FTE command” that supports forward action in the ACL tables (ingress/egress).
- Resiliency Special Error Event: Firmware uses error events to monitor the health of core transport engines, both Rx and Tx, and to detect if a system hang occurred and was not cured by other error mechanisms. Upon such detection, events are sent to the driver to perform any required action (e.g., software reset).
- QP’s Creation Time: Accelerated QP’s creation time
- SR-IOV LID based Routing Mode: SR-IOV default routing mode is now LID based. The configuration change is available via mlxconfig tool. Note that in such mode, the VF will get its own LID, hence the GRH is not required. Note: LID based routing support for vports is supported using SM v4.8.1
- Expansion ROM: Added PXE and UEFI to additional ConnectX-4 adapter cards. ConnectX-4 now holds PXE, x86-UEFI and Arm-UEFI

Bug Fixes:

- Added the option to avoid unintentionally powering off the backplane port cage upon reboot when in standby mode.
- Increased the Full Wire Speed (FWS) threshold value to improve EDR link results.
- Fixed an issue that resulted in “Destroy LAG” command failure if a VFs received an FLR while its affinity QPs were open
- When RoCE Dual Port mode is enabled, tcpdump is not functional on the 2nd port.

Known Issues:

- Health counter increases every 50ms instead of 10ms.
- mlxconfig tool presents all possible expansion ROM images, instead of presenting only the existing images.
- An Ethernet multicast loopback packet is not counted (even if it is not a local loopback packet) when running the nic_receive_steering_discard command.
- When a dual-port VHCA sends a RoCE packet on its non-native port. and the packet arrives to its affiliated vport FDB, a mismatch might happen on the rules that match the packet source vport.

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.
