I still think what e1000 is doing is way too aggressive. I know of at least one platform, sparc64, that doesn't even have enough prefetch slots on certain chips to support the number of outstanding prefetches you are issuing. One, maybe two, prefetches per RX skb processed should be more than enough. As demonstrated by Robert. Please reduce the aggressiveness of your prefetching, at least for the first implementation that goes into the tree. Ok? We can discuss doing more aggressive things in the future.
