This is great thanks for sharing.

I also want to point to this cilium blogpost:
 https://www.cilium.io/blog/2017/4/24/launch-of-bpf-xdp-documentation

eBPF is sort of the XDP programming language, and if you want to learn
the details of the BPF Architecture and know more about the instruction
set, follow the blogpost link to: http://docs.cilium.io/en/latest/bpf/

I believe people subscribed to this list is more interested in having a
toolchain like LLVM that allow us to write (restricted) C-code and
generate the eBPF assembler for us. Luckily the same document describes
how this works and why e.g. inlining is required, here:
