Subject: Tool: netperf-wrapper and qdisc bulking


I going to use the tool called: "netperf-wrapper", for testing my qdisc
bulking patches.  It is very useful for network measurements, that
involves running multiple concurrent instances of testing tools
(primarily netperf and ping)

For others to get easily started using this tool, I've written a mini-tutorial:
 http://netoptimizer.blogspot.dk/2014/09/mini-tutorial-for-netperf-wrapper-setup.html

I'm currently using it for testing the Head-of-Line blocking issues
that bulking packets from the qdisc layer can possibly cause.

For that I've added an extra test called "tcp_upload_prio":
 https://github.com/tohojo/netperf-wrapper/commit/1e6b755e8051b6

More detail on these test results will follow (likely next week)
