I'll see if I can find some time, but after a quick look I don't think
it has any changes relevant in this case, and the patches even apply
cleanly.
I also remembered another strangeness: MDI reads never generate an
interrupt (the corresponding flag is ignored), was that code (MID
interrupts) ever tested with some real-world driver (I expect there
is no driver using that feature?).
