OK, I see.

HT Capabilities element = Defined by hardware and software spec of the 
node. So it does not be modified after boot.

HT Operation element = Defined by surrounding environment and 
configuration of the node. So it could be modified after boot.

So, if the node supports HT40, HT Capabilities shows HT40 is capable.
Now, I understand why you rejected this patch.

But now, when disable_ht=1, no HT Capabilities element in beacon even 
though the node supports HT.

My trailing patch could solve the issue.
