I captured traffic by run this command
tcpdump -I dna0 -s0 -n -e -c 50000 -w test.pcap
>50000 packets captured
>50000 packets received by filter
After I tried to send traffic in another machine by run this command
pfsend -r 5 -n0 -i dna0 -f test.pcap
The result is that the received NIC loses packets because the traffic is
distributed just on 4 queues
ethtool -S eth2

What is the problem?
Did I wrong the tcpdump or pfsend configuration?
I want specify that I haven't the DNA license, I worked in demo mode
I received traffic with the original ixgb driver not whit DNA driver
Thanks
