I am trying to override the mac addr.
pretty sure you need to use NIC model specific utilities to do this, ifcfg-ethN won't do it. the hwaddr= in there is for finding the nic, not for reprogramming it.
ifconfig claims to support it:
hw class address<snip> Also, don't forget /etc/udev/rules.d/70-persistant-net.rules
I can't forget what I don't know. please point me to description of these rules?
It's used to assign names to physical devices via udev. How it works depends a bit on your version.
It's discussed as part of these tutorials:

Ah. A bit:
# cat /etc/udev/rules.d/70-persistent-net.rules # This file was automatically generated by the /lib/udev/write_net_rules # program, run by the persistent-net-generator.rules rules file. # # You can modify it, as long as you keep each rule on a single # line, and change only the value of the NAME= key.

# net device () SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="02:c3:04:01:77:c 3", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
===========================================
So I can pull that eth1 line that got generated error and change the eth0 line?
Well I did that, took the macaddr and hwaddr lines. restarted network and it was not finding eth0. And it added eth1 back into /etc/udev/rules.d/70-persistent-net.rules.
I cleaned that up, and rebooted. During the boot, I see the message:
Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization. [FAILED]
and once I get started, ifconfig reports eth1 again, and the eth1 line got added to rules. But the network IS working with addresses I want. But on eth1 with the errors about eth0.
So there seems to be something before rules that is needed to be edited, or there is some limitation on my driver(s).
