e100: allow bad MAC address when running with invalid eeprom csum
Seved Torstendahl <seved.torstendahl@netinsight.net> suggested to
let the module parameter for invalid eeprom checksum control the valid
mac address test.
If this bypass happens we should print a different message,
or at least one that is correct, maybe something like below
