I'm curious, how would this firmware-loading scheme deal with having multiple cards of this type installed? This seems like an unusual situation, but it looks like this patch will cause all of the cards to start up with the same MAC address due to the fixed filename. Instead of using a firmware file to load in the MAC address, might it be possible to move the persistent MAC setting to a simple udev rule which generates a persistent MAC address, saves it, then sets it each boot using a command like "ip link set wlan0 address XX:XX:XX:XX:XX:XX" ? This would remove the need to have this "fake" firmware file available at boot, provided that the driver can handle leaving the address unconfigured until userspace gets around to setting it. As well, it could be written to work with multiple cards easily, saving a different MAC for each.
