-v please. I can just rework userspace to allow going via xt_bpf
but its brain damaged.
This helps gradually moving towards move epbf for those that
still heavily rely on the classic forwarding path.
If you are open to BPF_PROG_TYPE_NETFILTER I can go that route
as well, raw bpf program attachment via NF_HOOK and the bpf dispatcher,
but it will take significantly longer to get there.
It involves reviving
https://lore.kernel.org/netfilter-devel/20211014121046.29329-1-fw@strlen.de/
as a first stage/merge goal.
