I guess, I should/could have placed the eBPF/XDP examples[3] in another github repo.

There is a Makefile in the directory[3] kernel/samples/bpf, so simply chdir into this dir and run 'make'. Just like you would do in the kernel tree[4].

I've also been touring with a tutorial talk, see latest here[5] [5] http://people.netfilter.org/hawk/presentations/LLC2017/XDP_DDoS_protecting_LLC2017.pdf I guess, I'll update the documentation a bit after your feedback, thanks. -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer
