Hi Johannes,

I am able to apply both your patches in my local tree(with very very
minimal conflict)
http://thread.gmane.org/gmane.linux.kernel.wireless.general/133172

I had started studying(understand) your patch. Please
let me know if you have already added support for the same
in userspace as well, we like to use your changes and possibly
add any changes that addresses rx_stats histogram as well

I will keep you posted for any other queries/ clarification,
thanks !
