That's the first reason, the second is that we also want to report 
the unknown value if it's not recognized by the driver. For u8/enum
parameters the value may possibly be set to a value older driver
doesn't understand, but users should still be able to set them to one
of the known ones.

We'd also like to add that to 'fw_load_policy'. WDYT?
