ixgbe driver - Linux - View current parameter settings

[Greg17]

Is there a way on Linux to view the current parameter settings for the ixgbe driver? I'm using version 6.06 of the Linux driver.

"modinfo ixgbe" seems to only show the parameter definitions.

The parameter I'm interested in is InterruptThrottleRate

Thanks.

Hi Greg17,

Thank you for reaching out regarding the ixgbe driver parameter settings on Linux. To assist you more effectively, could you please provide the following details?

Ethernet Adapter Model and Specifications

Driver Version: Are you using a custom or standard (upstream) driver?

Kernel Version

Additional Information: Are you facing any issues or unexpected behavior, or do you require general guidance?

Recent Updates: Have there been any recent updates to the driver, firmware, or OS?

Once we receive this information, we will be able to provide more accurate support.

Looking forward to your response.

Ethernet Adapter - NI PXIe-8238

Driver Version - xgbe 6.06

Kernel Version - 5.10.223-rt115

I'm trying to determine if parameters that we set are maintained after a reboot. Being able to check the current parameter settings for the driver would help us determine that.

Thanks.

Hi Greg17,

Thank you for your response.

As the NI PXIe-8238 is not an Intel product and falls outside of our support scope, we kindly recommend reaching out to the original equipment manufacturer (OEM) for detailed assistance with this product.

If you have any questions or require further clarification, please don’t hesitate to reach out.

The adapter uses an Intel chip and an intel driver (ixgbe). The question is about the driver. Surely there's someone there that could answer my question.

[Akshaya1]

Hi Greg17,

Thank you for your response.

Although the chipsets and drivers are Intel products for the OEM system, it is important to note that the drivers themselves are developed and maintained by the respective OEM. Additionally, If you purchased an OEM branded server or appliance, contact your OEM for a SW driver version that is compatible with your exact FW version. Using SW and FW versions that have not been validated to work together will affect performance, feature availability, and system stability.

We kindly request you to reach out to OEM for further assistance.

Isn't the driver maintained by Intel? I downloaded it from here:

Hi Greg17,

Thank you for your response.

Intel recommends using drivers provided by the OEM for your Ethernet adapter to ensure optimal performance and compatibility.. Using untested drivers from Intel’s website may result in unexpected issues.

You can find the firmware and additional drivers for the PXIe-8238 provided by the OEM at the following link: PXIe-8238 Firmware and Additional Drivers

For any further assistance regarding this product, we recommend reaching out to the OEM, National Instruments, for dedicated support.

NI doesn't provide a driver for Linux. I'm asking a question about Intel's ixgbe driver for Linux. I'm just trying to find out if there's a way to view the current module parameters. Is that possible?

[Simon-Intel]

Hi Greg17,

Thank you for your response.

I would like to inform you that the driver you referred to is not valid for the PXIe-8238 product.

For a list of products that are compatible with this driver, please refer to the following link. To the section where it says "This download is valid for the product(s) listed below.'

Intel Network Adapter Driver Compatibility

If you have any further questions, please feel free to reach out.

According to that page, the ixgbe driver supports devices based on the Intel® Ethernet Controller 82599 controller . The PXIe-8238 is based on the 82599 controller.

Hi Greg17,

Modinfo only will give you parameter definition, but you can use the below command:

modinfo ixgbe | grep InterruptThrottleRate

This will show the InterruptThrottleRate parameter.

As you mentioned, it appears that modinfo only displays the default value

Are you saying there is no way to see the current parameter value?

[Simon-Intel]

Hi Greg17,

Thank you for your response.

Please allow me sometime while I check internally with my resources. I will get back to you as soon as I have an update.

Hello Greg17,

Thank you for your patience, and we apologize for the delay in getting back to you.

You can use ethtool in Linux to find the information.

Please follow the steps below:

Display Ethernet Settings:

Run ethtool <device_name> (e.g., ethtool eth0) 

To view details such as speed, duplex mode, link status, and other hardware parameters.  

Display Optical Module Information: 

Use ethtool -m <device_name> (e.g., ethtool -m eth0) 

To check module details. 

Note: This command may not be supported by all NICs.

Please let us know if you need any further information or assistance, please do not hesitate to reach out.

Best regards,

The command in the previous response (above) does not display the InterruptThrottleRate. Is there no way to see what this parameter setting is currently set to?

Here is the output from ethtool -m:
