putting on hold, as I'd like to do a later investigation about wrapping https://github.com/libbpf/libbpf-bootstrap, which seems to work pretty well, in Go. |

May be we should move this script to another directory?
Here we are mixing c headers and bash scripts

My understanding is that this struct and the go struct RawStats have to be equivalent.
Anyway we could generate one from the other?

Unfortunately, I don't know any way (unless we create some kind of parser, which it would be a nice side project)

How can we make sure we fetch the correct version? libbpf comes pre-installed, or do we install it?

Libbpf is bundled with the Cilium library. We just need the headers for compiling the C code. I'll check if there is a way that we can fetch the Cilium's libbpf version. The destination machine does not need to install any extra library, as libbpf is only used to build the eBPF VM bytecode.
