Ah, ok! Good catch, I see your v3 on the ML ... added them to my setup [1],
but I cannot try them yet, as my board (accurate ethernet) is broken ...
I must first reanimate it (no debugger connected to it yet ...)

You are welcome. Currently all work is done automatically [2] ... I just
have to pass a list of patchworknumbers to my testsetup, and they get
automagically tested on the board ...

bye,
Heiko
