I disagree. Generic netlink is trivially extensible while radiotap
isn't, and I really don't want a radiotap parser in the kernel.
Secondly, a lot of notification items will only be given via netlink
anyway, like failed decryption or whatever, and we don't want to keep
all this in fake management frames.

I think Thomas suggested the scheme GET/SET/NEW but I don't really care.

should get a NEW prefix as well then? :)
