Config space endian-ness is currently a mess: fields are not tagged with the correct endian-ness so it's easy to make mistakes like instanciating config space in native endian-ness. The following patches adding sparse tagging are currently in my tree. Lightly tested. As a follow-up, I plan to add new APIs that handle modern config space in a more efficient way (bypassing the version check). That is still TBD. I also start with a version using gcc extensions, then switch to _Generic. This is helpful for backports to older kernels/older distros: _Generic patch can just be skipped. Michael S.
