We have third party SFPs in X710 "based" NIC. To be exact we some HPE servers which have a "HPE Ethernet 10Gb 2-port 562SFP+ Adapter" which uses an OEM X710 controller branded as HP. So it maybe that the HP SoC on the NIC is allowing us to use any SFP. We haven't added any kernel module load parameters to make that work or NVRAM hacks, we just flashed the NIC to the lasted firmware version upon arrival as a general good practice move and compiled the latest i40e & i40evf drivers. We have third party 10G SFP+'s (single more / 10Km / LC) working and 1G copper SFPs too, the ports are multi-rate. Again this may be something special about the HP NIC and the X710 controller is ignorant of the PHY <> MAC conversation or something. Cheers, James.
