=> I raise here a silly but real concern: the common assumption
a MAC address is unique to a physical interface is *false*:
the IEEE spec is loose and uses the term device, it is commonly
but *not universally* interpreted as NIC, i.e., there is at least
one important vendor which assigns a MAC address to the whole box.
