[Click] Click questions

[Roman Chertov]

Ask the Emulab support team to make the Click OS image available to
other experimenters.  I made it a while ago for my own research.

I was working with RHL90-UPDATE, and I made a lot effort manually resolving conflicts between the click patch and the emulab customized kernel. I was able to make it compile in the end, but when it came to linking, there were still 10-20 kernel symbols missing, either not implemented by the emulab kernel or not exported, spanning many different kernel source files. I wonder if you have any suggestions or if you are aware of any other people who have already done this.

I have a component in my router that does something like stochastic fair queuing, and I noticed that if I raise the number of queues, I am getting very bad thruput. I am thinking of putting all the queues and some other stuff in a single element. I wonder if that would help.
