I don't think you can do this - just tear down all aggregation sessions
- there are APs out there that will not re-establish them if you tear
them down, or only attempt a given number of times, etc. This will cause
interoperability problems.
OTOH, arguably we have worse interoperability problems today, and anyone
who configures PTK rekeying is deluded that it'll work properly, so
maybe that's not _that_ bad. Hmm.
