I have the same here but it doesn't freezes, it just doesn't works :).
(maybe it "freezes" because next step depends on the eth like RARP?)
I digged into LXT971 datasheet and 0x1200 appears to be correct. I was thinking
in add an module option to manually set it (and thus avoiding the need to use
ethtool). Any MII guru around to help us on this?
