Hi Yuri,
I’m seeing 8 TX and RX queues displayed.

Subject: Re: [Ntop-misc] Increase number of RX queues in use by ixgbe-DNA
What is the output of ethtool after loading the modules?
How many queues are displayed?

Hello,
I’m hoping someone can help me increase the number of RX queues that are in use
on my machine.
It’s an 8 core machine that is running the latest
NProbe - 6.12.130420
PF_RING ixgbe-DNA - 3.10.16-DNA
OS - 2.6.38-12-generic-pae #51-Ubuntu SMP Wed Sep 28 16:11:32 UTC 2011 i686
i686 i386 GNU/Linux
The ixgbe driver is loaded with the following command
insmod ./ixgbe.ko MQ=1,1,1,1 RSS=8,8,8,8
From the documentation it says that it will start the number of RX queues up to
the maximum specified above (8) or the number of cores, but it appears like it
is only starting 2. The last line in the following blurp confirms that.
$:/proc/net/pf_ring/dev/dna0# cat info
Name: dna0
Index: 16
Address: 00:25:90:13:8C:F2
Polling Mode: DNA
Type: Ethernet
Family: Intel ixgbe 82599
Max # TX Queues: 8
# Used RX Queues: 2
The following 2 commands work, starting on dna0@0 and 1
/root/nprobe/nprobe -i dna0@0 -w 1048576 -q <IP>:1111 -n <IP>:2055
--cpu-affinity 1 -t 30 -l 10 -u 1 -Q 2 -V 5 -S 10 -b 1 &
/root/nprobe/nprobe -i dna0@1 -w 1048576 -q <IP>:1112 -n <IP>:2055
--cpu-affinity 2 -t 30 -l 10 -u 1 -Q 2 -V 5 -S 10 -b 1 &
But using dna0@3 and above fail to start, see last 3 lines below.
root@CenturyLink-nprobe1:~/nprobe# /root/nprobe/nprobe -i dna0@3 -w 1048576 -q
66.112.11.90:1112 -n 192.168.10.1:2055 -n 66.112.11.90:20555 -a --cpu-affinity
2 -t 30 -l 10 -u 1 -Q 2 -V 5 -S 10 -b 1
