Hi Heiner

Ah, cool, these are the patches i was asking for, when you asked
about splitting Maxime's patches. There is one more in my tree which
converts the marvell10g to using this. I think that should be posted
as well. It makes it clear how this should be used, and it replaces
one of the patches in Maxime's set.
