The MAC address is not unique, it is diverse. Think about
the number of
devices using MAC address and the number of available unique
ID's per
manufacturer...for the past 20 years or so .
6 bytes - 16 million combinations per manufacturer ID
The possibility of getting a NIC with a duplicate MAC
address on your local
network in the same broadcast domain, is etremely low. but
is possible, it
has happened to people I've worked with.
a long story but, to summarize, that was one long horrific
night
of network troubleshooting.
as for flipping the field - I haven't a clue.
