I understand. The problem is: with NO-IR set, we can't configure an AP, 
since the AP is the initial radiator.

So we just could remove NO-IR so we can create and use APs in this range?

In this case, I will create a v3 of the patch that just removes NO-IR 
and keeps the documentation links as is.

Please let me know what you think.
