This was left out on purpose to avoid enabling some channels
(especially, anything requiring DFS). Similarly, HT40 negotiation is
quite unclear topic and it seems it would be clearer to just negotiate
HT20 and have the GO enable HT40 on its own.

What are you trying to achieve with the changes in this patch?

I'm not planning on enabling DFS channels for P2P use cases, so
especially this section would require quite a bit more justification.
