Andrew Gospodarek centralized the bnxt_hsi.h header file within the geerlingguy/linux repository, enabling consistent cross-driver usage for bnxt_en, bnxt_re, and bnge. By relocating the header to include/linux/bnxt/hsi.h and updating all relevant references, he established a single source of truth for BNXT HSI exposure, which streamlines future development and reduces maintenance overhead. His work focused on driver development, header file management, and kernel development, all implemented in C. This refactor improved code organization and cross-driver consistency, laying a solid foundation for scalable changes and collaborative development across multiple drivers within the Linux kernel codebase.
