XL710 stuck in 4x10G breakout mode

[Heinrich]

Good day,

I have a Intel XL710 (rev 01) that is stuck in 4x10G breakout mode. Using the latest QCU tool I am not able to set the device back into 2x40G

I have tried NVM version 8.3 and 6.8.

./qcu64e /nic=1 /info
Intel(R) QSFP+ Configuration Utility

QCU version: v2.34.17.03
Copyright(C) 2014 - 2019 by Intel Corporation.
Software released under Intel Proprietary License.

Adapter supports QSFP+ Configuration modification.
Current Configuration: 4x10

Supported Configurations:
4x10
2x2x10A
2x2x10B

Any advice on how I can revert the breakout mode?

Kind regards,
Heinrich

Hello Heinrich,

Thank you for posting in Intel Ethernet Communities. 

For us to further check the issue, kindly confirm if you are designing a system or a board with embedded XL710.

Can you tell us on how would you implement this and how are you using the QCU tool?

If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.

Best regards,

Hi Michael

No, this isn't a embedded design. This is happening on a 2x40GbE NIC. Previously the card was in 2x40 mode and I used the QCU tool to break out the ports into 4x10 but I am unable to revert them back to 2x40 again

Kind regards,
Heinrich

Hi Michael!

Please find attached the generated SSU. I will try to answer your questions in case the SSU does not contain everything needed:

1) Currently I am using CentOS 8.3.2011 with kernel 5.10.28
2) The XL170 NIC is bound to the in-tree i40e driver. (vermagic: 5.10.28 SMP mod_unload modversions)

3) Yes, this is a PCIe card
4) The card is installed in a SuperMicro server. (I see the SSU contains some more info on this)
5) SSU attached

Kind regards
Heinrich
