Chatted to an old guru about this yesterday and with zero hesitation he recalled a race condition triggered by a brief interface flap pulling on latent or inactive code for MAC spoofing that had zeros set as the default, rather than being populated with the regular MAC address.He has no knowledge of pfSense per se but it was interesting that his thought was contrary to mine in that pfSense software is probably the place to look.

Normally though if you spoof the MAC it appears as a separate line in the ifconfig output. It always reports the hardware MAC in addition. But, yes, certainly worth considering. If I could replicate this myself it would be a lot easier!
