Deleted all the back-and-forthing and will only include what finally
worked. Sheesh, I got buried in the cruft on this one.
Edit /etc/udev/rules.d/70-persistent-net.rules to have your REAL mac addr:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="02:c3:04:01:77:c3", ATTR{type}=="1", KERNEL=="eth*",
NAME="eth0"
Edit /etc/sysconfig/network-scripts/ifcfg-eth0 with the mac addr you want:
MACADDR=02:67:15:00:01:79
REBOOT!
running start_udev at this point only added the eth1 entry again. The
kernel was so confused that I needed to 'clean house'.
# ifconfig

I got my desired MAC addr, my static IPv4 addr, and IPv6 RA + MAC =
desired IPv6 addr.
Now to reveal why I went to these efforts. STATIC IPv6 is badness when
you want to be able to change prefixes but have 'nice' IPv6 addresses.
So I studied how IPv6 suffixes are currently constructed, decided what I
wanted, and off to the races.
Well another reason, is I will be working in IEEE 802 MAC privacy Study
Group, and wanted to see what COULD be done to create privacy-enhancing
MAC addresses.
But thank you ALL for your efforts!
