No transmit packet counters on client GUI with PF_RING DNA

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Compile ostinato source with PF_RING support
2.load PF_RING 6.0.2 kernel module and 10G DNA driver for Intel 82599
3.Run Ostinato and setup IPv4 stream on DNA interface

What is the expected output? What do you see instead?
I would expect transmitted FPS counter to work.  No counters work

What version and revision of the product are you using (available in the
About dialog)? On what operating system?
Ubuntu 14.04 PF_RING 6.0.2 Ostinato .6 from source clone.

Please provide any additional information below.

- Can you elaborate on how you compiled PF_RING DNA support into Ostinato?
- Please attach startup console log of drone for analysis

I compiled the PF_RING support be editing the obstinate/server/drone.pro with 
the following

LIBS += ~/PF_RING-6.0.2/userland/libpcap/libpcap.a -lpfring -lnuma -lrt

attached is startup log.

I see the above in the log - not sure if it is because of that. But as per the 
msg you do have 5mins worth of transmit even without a valid license - you did 
click on "apply" and "start transmit" - right?

Ostinato has different methods to collect stats on Linux and I see that it is 
using the netlink method (the preferred method) in your case. You might want to 
check with the pf_ring dna folks that netlink stats will work as expected with 
pf_ring dna.

Check /proc/net/dev and see if you see stats increasing for the pf_ring dna 
ports. If so, you can try the following change -
You could also 
void LinuxPort::StatsMonitor::run()
{
-    if (netlinkStats() < 0)
+    //if (netlinkStats() < 0)
    {
        qDebug("netlink stats not available - using /proc stats");
        procStats();
    }
}
