I don't agree; these firmware files are updates for the flash and only
need to be loaded once.

Also: this driver's behaviour of automatically updating flash without
any confirmation seems quite dangerous.  The driver also isn't usable
after it performs such an update:

	printk(KERN_NOTICE "Upgrade of firmware successful!  Adapter must be "
	       "hard reset before using, thus requiring a system reboot or a "
	       "hotplug event.\n");

So what is the point of integrating firmware update into the driver at
all?

Ben.

It is easier to change the specification to fit the program than vice versa.
