I have a NVIDIA Corporation MCP61 Ethernet which mac address changes eveytime I reboot my box.
[root@sun etc]# dmesg |grep eth0
forcedeth 0000:00:07.0: ifname eth0, PHY OUI 0x732 @ 1, addr 66:b6:95:ea:3e:29
udev: renamed network interface eth0 to eth3
udev: renamed network interface eth0 to eth1
This time it’s 66:b6:95:ea:3e:29. How to avoid this?
This is offtopic for here, but its a known bug for a long time. See this extensive discussion at Ubuntu’s bugtracker.
It also has a fix proposed some 10 years back.
I know its Ubuntu’s bugtracker, but the problem is with the linux kernel drivers. The link there will lead you to some work arounds to solve the problem.
