Will this (x520-10g-1s) work on a qnap tvs-h1288x?

We noticed that intel official website does not provide QNAP driver, but the X520-DA2 and X520-SR2 NICs are listed in the device support list for QNAP TV-H1288x, so we suggest that you can further confirm with QNAP technical support or buy one for testing.
