Freebsd IP Forwarding performance (question, and some info) [7-stable, current, em, smp]

[Paul]

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.
