Different hardware requires different configurations, and this distinction was not made previously. Additionally, the error message was not clear enough. Therefore, in this patch, the following changes have been made to address these issues: 1. Sets tp->hw_ver. 2. Changes the return type from bool to int. 3. Modify the error message for an invalid hardware version id.
