It looks pretty simple: we need two separate events for the filter: polled and AN media change notifies. We should be able to turn either of them off, so two separate flags. They need to be unified into the single media change event at the top of the stack before we call udev. This will allow us to turn off the AN notifies if we get a problem, which was the original idea. > These events are for non-AN devices, which we still poll for media > changes.

I take it all you want is an indication that we will be using AN instead of polling, which you will be able to get from the sysfs file.
