Hey! Nice blog post! Thank you. Did you study the idea of using bpf_tail_call to create "reusable"/"hot-pluggable" programs, linking them together by BPF_MAP_TYPE_PROG_ARRAYs updated dynamically from userspace? A sort of Warhammer Quest-like dungeon for packets.

There is a limit of 32 tail calls. We do however utilize several eBPF programs linked together with tail calls each handling things like sampling, or different classes of rules.
