nking about create a stateless rule.

I suspect this will only decrease your packet rates.  From what I
understand, state table lookups are MUCH cheaper than rule table
lookups.  Also, the congestion count increases (from memory) when the
nic can't send packets, you might look at increasing then
net.inet.ip.intr_queue_maxlen sysctl if net.inet.ip.intr_queue_drops
is showing a non-zero value (which it likely is if you are pushing
400kpps w/out increasing the queue).

BTW, what version of FreeBSD, I didn't see it already mentioned in the thre=
ad.
