Just an update to point to another old patch that enable flowtable on =
the forwarding path to increase performance (reduce contention) to be on =
par with Linux:
http://people.freebsd.org/~fabient/FreeBSDvsLinux10GB.png (forwarding =
256B packets, % to line rate on 2x10Gb 82599 interface with 1xXeon =
W3680)
http://people.freebsd.org/~fabient/patch-flowtable-forward

Coupled with the polling code it perform quite well.

Last things a latency / polling overhead test result:
http://people.freebsd.org/~fabient/polllatency.png

User app is the time it take to run a CPU related benchmark (lower is =
better), net load is fixed as high but let some CPU available.
Freq is the HZ for polling or the measured intr frequency for that load. =
Latency is measured by Spirent STC.
