Mellanox MCX312A-XCBT rev.A2 Network Card Firmware 2.40.5000 Description

Bug Fixes:

- Added the option to transmit corrupted DME pages for a very short period of time at the beginning of the Auto-Negotiation flow.
- Auto Sense: Fixed an issue where in rare cases the Auto Sense failed to detect the right protocol.
- Signal Integrity: Fixed signal integrity issue when connecting a WCS ConnectX4 mezz card to Pikes peak FPGA.
- Counters: Fixed an incorrect report of the PortRcvDataVLExtended/PortXmitDataVLExtended counters by the firmware.
- Firmware’s Packet Injector: Fixed a rare issue which caused firmware’s packet injector to cut off packets when the TX was congested.
- TX requests: Fixed an issue that caused the response to TX requests to take up to 10 mili-seconds in IEEE clause 72 Link Training.
- ECN: Fixed a race between 2 iriscs which caused a QP to get stuck in burst control limit state
- CQE: When a QP was in error state, the firmware generated too many err CQEs at once, thus causing the cmdif responsiveness to be too slow. To prevent the above, the number of err CQEs was limited to 16 at a time.
- MAC address: Fixed an issue that caused the MAC address that was set from the OS using ifconfig to be not reflected in the OCBB buffer.
- ibdump: Fixed an issue where the ibdump got broken when running with loopback traffic.
- QP to Firmware ownership: Fixed an issue where the firmware took QP to firmware ownership and then released it to the hardware ownership without checking if another firmware flow owns the same QP.
- Cables: Fixed an issue which occurred after disconnecting cable which showed the link type as IB even if the link type of the port is ETH.
- HCA PoerXmitWait counter: Fixed an issue related to the HCA PoerXmitWait counter on port 2 (connected to port 2 on Switch-IB) where it started counting and reached 0xFF's regardless of connection to switch.

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.
