I have a XL710 adapter that I am unable to get setup. I am trying to set the mode using the qcu64e utility without any success:
# ./qcu64e /NIC=1 /INFO
Intel(R) QSFP+ Configuration Utility
QCU version: v2.26.17.06
Copyright(C) 2015 by Intel Corporation.
Software released under Intel Proprietary License.
QSFP+ Configuration modification is not supported by this adapter.
Here is the adapter I have:
# lspci | grep -i xl710
81:00.0 Ethernet controller: Intel Corporation Ethernet Controller XL710 for 40GbE QSFP+ (rev 02)
81:00.1 Ethernet controller: Intel Corporation Ethernet Controller XL710 for 40GbE QSFP+ (rev 02)
Any help you can provide would be greatly appreciated.
