 I looked at the other ath driver and I see no indication that it's related
 to DFS in any way.

 I have verified this just now as well, it seems it was only used to
 support an ioctl to userspace to enable users to update a tpscale
 value but I see no documentation about this. Next question is who in
 usersapce sets this. I wonder if its done through userspace after
 measuring some TPC reports from STAs.

So this comes from supporting a "TR-098" specification, which seems to
be the "Internet Gateway Device data model for the CPE WAN Management
Protocol". I haven't yet been able to map this to the specification
respective component:

Interesting. That definitely supports my point that ath9k is the wrong place for something like this to be. Let's just get rid of it.
