Hi Jouni Malinen,

Thanks for comments.

As you know, implementing ieee80211ah fully usable would be a very long 
journey, and reviewing the patch would be a big task.

For example, it should support operation at a frequency in KHz and a 
bandwidth of less than 20M. And since channel index and frequency matching 
are different by region, it is necessary to implement 
"frequency<->channel index converting" for each region.


So, before doing big task, I want to confirm that you are interested in 
adding the ieee80211ah feature to hostap. 

So, in this patch, I would like you to review the definition of hw mode 
And errors that occur when using ah mode.

Regards,
