Hi,

   Could you tell me how to use a patch to add codel to my ns3 simulator? The version I use is ns-3.15 and I use Ubuntu 12.04. I follow the steps in this web site http://www.bufferbloat.net/projects/codel/wiki but I still get error like this. I don’t know how to enable codel and I hope that you could help me. Thanks a lot!
