As was already mentioned, we can't avoid all cache misses as there's data

However, we may hide some of the latency penalty by prefetching

Will someone confirm if it will support the 82571EB ? I don't see a
reason why not as it's very similar hardware
and it's available now in large quantities so making 82571 part of igb I
think would be a good idea.

I found Andre Oppermann's optimization patch mentioned in july 2005
status report:
http://lis
But this is probably no routing table, and single source and dst ips or
very limited number of ips and ports.
the entire problem with Linux is the route cache, try and generate
random source ips and random source/dst ports
and it won't even do 100kpps without problems.
