I am not sure i see the complexity in the wireless driver's wakeup
strategy. I just gave some suggestions to use management frames - they
dont have to be literally that way.

There will be some shared code on drivers of same media on the
netif_stop/wake strategy perhaps, but not related to queue management.

Why is it not accurate for wireless? I can see the corner case Patrick
mentioned in wired ethernet but then wired ethernet doesnt have other
events such as management frames (actually DCE does) to help.
