I have some mellanox cards I've been testing in unraid and I get duplicate Mac addresses. Attached are 2 screenshots and diagnostics. You can see I have duplicate Macs in the network section and when I try to reassign them it states I have duplicates (doh!). Last screenshot shows card itself only has the normal 2 Macs, 1 per port. Interestingly, I seem to get a Mac duplicated at every reboot.
Edit: Card is MCX312A (dual port) and MCX311A (single port) - single port works great and shows 1 Mac. Both dual ports I tested with showed any number of duplicate Macs depending on when I tested.
Edit2: eth0, eth1, eth2 are all fine, and show up. I have an eth4 that has the duplicate Mac on it, and occasionally eth5. Those are not visible on the network page except in the assignment section.
