This doesn't look like xsk.h header from libbpf, but it looks like kernel's internal xsk.h instead. I'm not sure how you end up installing that header to the /usr/include/, it should not be there. If you copied this header from the kernel, undo that. On Ubuntu you may install libbpf-dev package instead of building libbpf from kernel sources.
