In this patch the text in the Kconfig help text is what we go by. The
description about the MAC address in the patch description is not 100%
accurate as the MAC address is read from EEPROM, not firmware. In this
patch the goal is just to not have the driver built in, but a module.
This ensures that firmware can be loaded at a time when the filesystem
is available.
