This sounds like a PHY issue, and that level
Of issue is usually some SFP+ module compatibility issue. 

The 10GIG MAC in the X310 is implemented in the FPGA, and I believe uses Xilinx Modules within the FPGA.

Now we are in a situation to find the root cause of this. Either the HW/SW at PC side is causing the issue or HW/SW at PC side is not compatible with SDR.
