Hi Guenter

I just started doing some testing with this patchset. A bit late since
David just accepted it, but...

root@dir665:~# ethtool -e lan4
Cannot get EEPROM data: Invalid argument
root@dir665:~# ethtool -e eth0
Cannot get EEPROM data: Operation not supported

There is no eeprom for the hardware i'm testing. Operation not
supported seems like a better error code and Invalid argument, and is
what other network drivers i tried returned.
