Hi Michal,

Here is our last findings from ACS feature in hostapd
http://article.gmane.org/gmane.linux.kernel.wireless.general/109945

We can give users some option to choose from different ACS
algorithms. Eg., Simple scan based algorithm or Advanced algo which
requires off-channel rx/tx support from the driver.

Thanks
Yogesh
