Are you even sure it's NetworkManager messing with your MAC addresses? I
have no idea why NM should ever mess with MAC addresses on a server and I
don't expect NM is doing so.
I have another idea: Seems this is on a SuperMicro server, can it be that
the box in question has a shared lights out management, sharing the
management ethernet port with the first LAN port? If so, can it be that
the management port is not configured properly and does try to DHCP an
IPv4 address? If you don't need the management stuff then you may try to
simply disable it to get rid of the mess.

Simon
