Unfortunately, that is not how UAPI works. That change breaks building
of the existing code; one cannot change already released versions
of either audit, strace, or any other userspace program that happens
to unconditionally include <linux/ipx.h> without any fallback (like
<netipx/ipx.h> provided by glibc).
