Subject: [PATCH] Seved Torstendahl <seved.torstendahl@...insight.net> suggested to

From: Jesse Brandeburg <jesse.brandeburg@...el.com>

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
