Okay so I built "iw" version 0.9.22 successfully (after much grief).
The help page shows that "set bitrates" is now supported:

        dev <devname> set bitrates [legacy-<2.4|5> <legacy rate in Mbps>*]


 but when I try to use it I get:

       # iw dev wlan0 set bitrates legacy-2.4 1 2 5.5 11
       command failed: Operation not supported (-95)

...so what does this mean?  Is it "iw" or the driver that lacks the support?
