[Click] Click Vs Packet Manglers

[Eddie Kohler]

Well, you can read our papers.  But essentially Click is more flexible 
and gives you full control over the whole forwarding path.  One can 
arrange several stages of mangling/QoS in arbitrary order.  Also, Click 
is not by default part of the kernel; it is intended for research 
(people do use it in products, it's stable, but nevertheless).
