Right, but Bernhard points out the original code did return its own
configuration, and this causes some APs to reject stations.
Hence why it's doing this.

I don't think so. The whole point here is to _support_ nodes whose
density/ampdusize is less than what we have configured. The only
reason we'd want to reject them is if we have some concept of "minimum
acceptable density/ampdurx" (like "minimum basic rates"), rather than
"what is it we support."
