2. Performance Enhancements
- aggressive prefetch of rx_desc and skb->data just like we do for 10gig
- align the prefetches to a dword to help speed them up
- copybreak for packets < 256 bytes, ideally we would like to modify ethtool to
allow this value to be changed, helps small MTU, many reassemblies case
- Fix RX buffer size changes
- Fixed Jumbo frames and memory allocation
rejected patches 2-8, since prefetch is still apparently under
discussinon and tuning. It sounds like there are some interesting
copybreak suggestions (applicable not just to e1000), and that 2
prefetches is the e1000 sweet spot...?
