You don't need policing for the forcing a ceil, htb can this too.

Do you know how slow 10Bps is ?????   Use some real values like 10KBps or so.

Do you want to shape outgoing traffic or incoming traffic?  Ingress is for 
incoming traffic, htb is outgoing traffic.
You can use htb for incoming traffic if you use the imq device or if you can 
shape on a router, you can shape on both interfaces.
