Nice work. Because this is such a significant change, and to maximise testing
time, I'm planning to queue this for 4.9 (so I would apply this to ath-next in
3-4 weeks after the merge window closes). But anyone who wants to test this can
use master-pending branch from my ath.git tree (uses wireless-testing as the
baseline). Sounds good?

Testing and review feedback very welcome!
