[Cerowrt-devel] Problems testing sqm (solved)

[Dave Taht]

in terms of testing wifi, the most useful series of tests to conduct
at the moment - since we plan to fix per station queuing soon - are
the rtt_fair tests, against multiple wifi stations. Run it all against
one station, then 2, then 4.

I just invested five years of my life to making wifi better. And,
now... the FCC wants to make my work, illegal for people to install.

I have not tested whether this is required for 10.10 or 10.11, in any way installing all under macports is nice because to clean up afterwards all you need to do is remove /opt/local...
