[Click] peak packet forwarding rate measurement

[Eddie Kohler]

If you are running a kernel configuration, the handlers are available 
in the /click filesystem.

If you are running a user level configuration, you can include a 
ControlSocket element and telnet to the router to see handler values 
(man ControlSocket).

Either way, you can include a PokeHandlers element to print handler 
values periodically (man PokeHandlers).
