Policers are not very good in practice, consider using ifb.
Either way policing/shaping ingress traffic is not totally controllable
like it is on egress.
I send this nping command with the --data-length extension so that the
ping will not be treated as a single bit.
If htb/bfifo is not backlogged then the packet will get sent instantly
whatever length it is.
