[Click] [click] how to print out queue size

[Soon-Yong Sohn]

Hello,

I would like to figure out how to print out the queue size.
I implemented Queue(200) element in interface and want to print out the queue size during routing process using PrintQueueSize(). 

Followings are my click configuration.
Please let me know how I can get queue size of the interface.
Thank you

Eric
