| NAME="eth0"

| Jan 18 18:09:50 hermes kernel: [64594.332000] 0000:00:0a.0: Invalid Mac
| address detected: 8d:08:f2:d3:16:00
| Jan 18 18:09:50 hermes kernel: [64594.332000] Please complain to your
| hardware vendor. Switching to a random MAC.
|
| This corresponds to the ethernet controller device in my lspci output:
|
| 00:0a.0 Ethernet controller: nVidia Corporation Unknown device 054c
| (rev a2)
|
| The MAC detected is the reverse of the real MAC address.  How do I
| either tell udev to reverse the detected MAC address, or to not try and
| create new ethX devices and force eth0 to use the proper MAC?

Yes, and it occurs for each re-installation as well.  The wireless
interface doesn't have this problem.
