Hi Jacob

Maybe add a --dry-run option? That would allow the driver to also read
the firmware file, make sure it can parse it, it fits the actual
hardware, and the CRC is O.K, etc.

We just need to make sure that if it fails with -EOPNOTSUPP, is it
clear if --dry-run itself is not supported, or the operation is not
supported. extack should help with that.
