Ideally we would allow a blend of tracing and networking programs,
then the best solution would be one or two stable tracepoints in
networking stack where skb is visible and receiving/transmitting task
is also visible, then skb->len and task->pid together would give nice
foundation for accurate stats.

I think combining both seems interesting anyway, we need to find
a way to make this gluing of both worlds easy to use, though. It's
certainly interesting for stats/diagnostics, but one wouldn't be
able to use the current/future skb eBPF helpers from {cls,act}_bpf
in that context.
