Great, I agree this is the correct approach, and that's why I wrote in my earlier email:
"I'll of course monitor the PPC code upstream and if they will manage to push a fix to their current DMA mask limitation (that will allow setting dma mask of 48 bits and without setting bit 59 in outbound transactions), I will modify my code accordingly and then this hack won't be necessary. But for now, it is what it is."
So I don't get it why you object for this temporary fix in my driver.
Thanks, Oded
