...remembering that duplicate MAC addresses aren't actually a
problem unless you get two of them on the same broadcast-domain LAN.
Within an 'IP Core' there usually aren't many high-node-count
broadcast domains. Many many point-to-point real or virtual links
with 2 addresses, many VLANs with less than 20 nodes perhaps.<br>
<br>
If you managed to get duplicate MACs into the same broadcast domain
in a cellular control node or something, I'd hope that it would be
found during testing when everything failed to operate properly, and
be fixed before the node went into production.<br>
<br>
On the other hand corporate/enterprise LANs and cube-farms, with
hundreds or thousands of devices per floor...(shudder)<br>
