> eBPF has a graceful approach: it must successfully compile on all Linux
> distributions. If a specific kernel cannot support eBPF it will gracefully
> refuse the eBPF netlink message sent to it.
> The kernel header file linux/bpf.h (if present) on different Linux
> distributions may not include all definitions required for TAP
> compilation.
> In order to guarantee a successful eBPF compilation everywhere all the
> required definitions for TAP have been locally added instead of including
> file <linux/bpf.h>
