This is one of those cases where the changes seem to be of general
interest, but there is no immediate plans to work on any upstream driver
to use that. As far as the current potentially applicable upstream
drivers are concerned, I would not expect ath6kl to be extended to use
this. I do not really know whether anyone maintaining the drivers for
other vendors would be interested.

This is a balance on what would be the cleanest design (i.e., the most
appropriate nl80211 command for this type of configuration) and
potential help for others vs. what could be done with a somewhat ugly
vendor specific command before the start AP command. Since this specific
case can be handled with a vendor command, I'm not planning on pushing
strongly for this to get accepted into upstream nl80211, but it did seem
to make sense to propose this to see if there would be sufficient
interest for other drivers.
