 * INPUT PARAMETERS
 *
 * nd_family corresponds to the firmware (e.g. DSM) interface.
 *
 * nd_command are the function index advertised by the firmware.
 *
 * nd_size_in is the size of the input parameters being passed to firmware
 *
 * OUTPUT PARAMETERS
 *
 * nd_fw_size is the size of the data firmware wants to return for
 * the call.  If nd_fw_size is greater than size of nd_size_out, only
 * the first nd_size_out bytes are returned.
