[PATCH] Be careful about memory ordering in sungem driver
Some barriers between setting up the DMA regions and writing the descriptor addresses would be most useful. I had some in my 2.4 version but they got lost someway, probably me not properly merging with davem at this point. The 970 is definitely more agressive at re-ordering stores than previous CPUs... Here is a patch adding some (probably too much, but better safe than sorry).
