I just checked. It has "Permanent HW addr", which is NOT changed by `ifconfig .. hw ether ...'. This at least serves as a workaround for those interfaces I have bonding on. Thank you! I can't get dmidecode to show the real MAC address. BTW, I got in touch with an author of ethtool. He provided a patch to expose perm_addr as a command line option for ethtool. I haven't run patch for too many years so for now I'm just waiting for the patched source to be available.
