So for every packet processed, you want to require the user to load
and run a (unJITed) nft program acting as a wrapper to run a JITed
BPF program? What it the benefit of this model compared to what Daniel
is proposing? The hooking point is the same. This only introduces
additional per packet overhead in the fast path. Am I missing something?
