Thank you for answering.
I understood to use ./qcu64e /nic=1 /set=4x10 command for setting breakout mode.
However my question is that, I couldn't set it to 4x10 mode due to the error message I have as below:
[root@centos12 qcu]# ./qcu64e /nic=1 /info
Intel(R) QSFP+ Configuration Utility
QCU version: v1.24.35.01
Copyright(C) 2015 by Intel Corporation.
Software released under Intel Proprietary License.
QSFP+ Configuration modification is not supported by this adapter.
I downloaded Intel® Network Connections Software from below link.
I tested from 20.0, 20.1, 20.2, 20.3 and 20.4.1 which is the latest version, however when I ran qcu64e, the message shows N/A mode.
I'd like to see 2x40 mode or something like that, so I can program it to 4x10 mode or so.
Could you please let me know why I couldn't see the mode of adapter with valid option?
Please let me know if you need any more information.
