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

Any help is much appreciated!
