The pds_fwctl driver doesn't know what RPC operations are available in the firmware, so also doesn't know what scope they might have. The userland utility supplies the firmware "endpoint" and "operation" id values and this driver queries the firmware for endpoints and their available operations. The operation descriptions include the scope information which the driver uses for scope testing.
