This brings policy into the kernel. Why should TX data be more 
important than a scan result?

If an app only gets partial scan results because of "too much tx 
data", what can the app do against it?  Nothing. It can just 
retrigger a scan again. But what if then there is still "too 
much tx data"?  Then the times of n * "partial scan" might be 
bigger than a "real scan" and a happy application.
