This patch allows you to set the iSerialNumber field in the
usb_device_descriptor structure for your USB ethernet gadget.

It also changes the parameters shown through sysfs so they're
no longer declared as __initdata, preventing potential oopses.

That's most useful for the Ethernet addresses, which may in
some cases be random "locally administered" addresses.
