The advertised rate set should be initially set according to the 
capabilities of the device.  There were no devices > 2x2 when I wrote 
the code so MCS15 is the max.  To support such devices you need to do 
more than just grow the rateset.

Making the rate set user-controllable would be ok to add but probably 
used only for testing.
