Yeah, I realized that indeed the policies in the kernel only cover validation *to* the kernel. In iw the policies are used rarely and most type information is covered in the code. py80211 relies on policies to obtain the type information and I was hoping to extract it from the kernel/iw code. I may end up maintaining it in py80211. Gr.
