Also, don't you have phy changes > since the init sequence differs between 845 and 8998? Will create a specific binding. I don't have any PHY changes, I just used the 845 init sequence. I tested this by using the 845 init sequence downstream. However, no point in sending v3 until someone comments on patches 3 and 4 :-) Patch 4 needs to become a real patch. Regards.
