Hello!
I'm using PF_RING 6.0.2 with Debian 7 Wheezy 3.2.0-4-amd64. I
installed ixgbe driver with ZC support and loaded it with
load_driver.sh.
I don't need any processing and linux stack thus I set: transparent_mode=2.
After this I run udp flood from 6 hping instances from another server:
hping3 -I eth1 --udp --flood 10.10.10.200
After this I run top and got this:
%Cpu(s): 0.0 us, 0.0 sy, 0.0 ni, 90.3 id, 0.0 wa, 0.0 hi, 9.7 si, 0.0 st
3 root 20 0 0 0 0 S 78.5 0.0 5:40.02
ksoftirqd/0
htop looks like this:
1 [||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||93.9%]
Tasks: 24, 3 thr, 49 kthr; 1 running
2 [
0.0%] Load average: 0.05 0.20 0.22
3 [
0.0%] Uptime: 18 days, 22:04:44
4 [ 0.0%]
Mem[||||||||||||||| 2661/32207MB]
Swp[ 0/8190MB]
I even tried to enable quick_mode=1 but ksoftirqd consuming almost
whole CPU core.
Thank you for your attention!

Sincerely yours, Pavel Odintsov
