[Click] SimpleQueue and ToHost

[Jelena Mirkovic]

I think I don't quite understand push and pull concepts :) but when I  
try the code

FromDevice(eth2)        -> classifier
                         -> Print(ok)
                         -> SimpleQueue(10)
                         -> ToHost;

I get an error 'SimpleQueue at 4 :: SimpleQueue' pull output 0 connected  
to 'ToHost at 5 :: ToHost' push input 0

What am I missing? Shouldn't pull outputs always be connected to push  
inputs?
All I want is to pass packets through a queue and send them along  
their way as they were going before the queue. This is a piece of  
kernel code.
Thanks!
