How to enable multiqueue on xl710-q2 iavf driver

StrongXiong — Wed, 31 Aug 2022 14:07:05 GMT

Hi,

I am try to check the irq balance function on xl710-q2 RHEL VM on hyper-v host

I enabled sr-iov and can see the vf using driver: iavf

But always Multiqueue Disabled:

16.856543] iavf 4ec9:00:02.0: Multiqueue Disabled: Queue pair count = 1

ethtool -l enP20169s2

Channel parameters for enP20169s2:
Pre-set maximums:
RX: n/a
TX: n/a
Other: 1
Combined: 1
Current hardware settings:
RX: n/a
TX: n/a
Other: 1
Combined: 1

How to enable more Combined here?

Thanks

Strong

Hello StrongXiong,

Thank you for posting on Intel Ethernet Communities.

We would like to check first if you are using a discreet network adapter or an embedded controller for your XL710-Q2 that you are using.

If you are using a discreet/pcie adapter, please provide us a picture of the markings both front and back so we can determine if its a retail or an OEM adapter. However if you are using an embedded controller, please provide us the exact model of your mother board.

Also we would like to ask what will be your main purpose/goal? Why are you needing to check the irq balance function? Please advise us so we can fully understand your purpose and provide you an accurate recommendation.

If you have questions or other clarifications please let us know so we can help you further.

Awaiting to hear from you soon, should there be no response from you, I’ll make sure to reach out after 3 business days. Thank you and have a nice day!

Best regards,

Hi Zigfreid I,

I am working remote, and cannot take photo for the card. I am a test engineer, and just need to check this case was worked as expected. I also checked mellonax, and want to check with Intel card in the same time.

I found some guilde but not work:

https://dl.dell.com/manuals/all-products/esuprt_data_center_infra_int/esuprt_data_center_infra_network_adapters/intel-pro-adapters_User's-Guide_en-us.pdf

[ 395.647707] iavf: unknown parameter 'Multiqueue ignored

So is there any public guilde for the iavf driver configuration of Multiqueue?

Thanks

Strong
