Making WiFi fast

while we are working on various modifications to fq_codel to make it more robust across a wide range of rates and numbers of stations, the airtime fairness patches we have currently do indeed behave better than what we call the fq-mac version without an explicit modification to codel.

I certainly welcome more testers (see the links to patches I posted earlier), ideas, and data. In addition to the data on the slides there, we have a large paper on the airtime fairness stuff pending academic review, which I can provide privately if you would like to see it.
