I believe connectx2 work using the plus kernel, however look for a connectx 3 or 4 either native Ethernet (EN) or a VPI variant, these will be 40Gb and you can use a qsfp to sfp+ convertor, or 40Gb transceiver (auto negotiated to 10Gb).

You can change the port profile using mellanox tools or editing the profile in /says.
