For what it's worth:

I just upgraded my test AP from the initial AC 3168 to an AC 9560 card 
after the AC 201 turned out to be incompatible (for now).

So I can now confirm that Extended Key ID is also working with this card 
and the patch here. (Tested against my "reference" system using an old 
Intel Ultimate-N 6300.)
