Hi!
I am trying to use one of the dual port XL710 adapters to connect with a 10Gb port. For that, I am trying to use an adapter from Mellanox: MAM1Q00A-QSA Cable Module ETH 10GbE 40Gb/s to 10Gb/s QSFP to SFP+. Unfortunately, just plugging it into XL710 and connecting the resulting SFP+ does not lead to an established link. So, I wonder, whether XL710 supports such configuration? My setup:
OS: Ubuntu 14.04
lspci -v:
