Alfredo et al.,
Thanks, I was able to load the ixgbe DNA driver with the modified load_dna_driver.sh (with RSS=0,0,0,0) script but, now …
I am not sure how to call the interface with pfcount or tcpdump or whatever to avoid capturing only "from the first one ("-i dna0" == "-i dna0 at 0")".
I am trying this:
[chl at sensor1 src]$ sudo pfcount -i dna0
How should I call the interface in order to capture all of the queues?
Thanks for your help on this.
