    duplicate MAC address of two different X520-DA2 NICs




      my question is directed to Intel NIC developers - we (CDN77) are using your X520-DA2 cards in thousands of servers - we have discovered that two different X520-DA2 NICs we have in our network do use the SAME MAC address.


      The conflicting MAC is 00:1b:21:bc:32:15.


      Is this something what 'can happen from time to time'? It would be a real flaw in the design - this makes makes me think the duplicate MAC is caused by some Chinese copy of the genuine Intel NIC.


      You can imagine what mess can this cause.


      If it helps, I can send more detail information regarding both NICs.



      Thank you!
