The real fix appears to be sending probe req in response to a h/w bmiss 
before dropping the ap. The phantom bmiss stuff just helps reduce the 
number of probe req frames.  I couldn't tell from the commit msg whether 
the code to send a probe req was added.

I think you mean the calibrated noise floor.

This is old (and was not a release); 0.9.16.16 is a release that has 
fixes to 0.9.16.13 and also disables DFS.

sparc64 works (tested by Martin) and BE ppc elf is know to work.  The 
alpha build is the untested code.
