[Click] SimpleQueue and ToHost

[Beyers Cronje]

Jelena,

No, pull output should be connected to pull inputs. As Roman indicated you
can leave out the queue in this config, but I presume you want to test some
queueing function, in which case you can use one of the pull-to-push
converters such as Unqueue. Have a look at all the Unqueue elements over at
http://read.cs.ucla.edu/click/elements

Example:

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