We can fill out the struct and append it to the basl_table by using basl_table_append_bytes. After that, we have to declare which checksums, length and pointers should be patched by basl. That's done by the add_* functions. Reviewed by: jhb, markj Approved by: manu (mentor) MFC after: 2 weeks Sponsored by: Beckhoff Automation GmbH & Co.
