I have tried few tests by trying to turn on TSO , but according to my
observation, ovs-dpdk doesn't support TSO Offloading.
You can try this reference from the following page:

Hi users,
I need to get the average time spent in packet extraction then in first
level cache , second level cache. I don't know the way to measure that.
Can anyone please help me pointing to right direction?
I think, I need to modify some code. Please guide me if I am right or wrong.
Looking
and packet header
extraction?
If yes, please tell me the way to do that? Which part I should perf for?
Thanks and Regards

Hello everyone
I am testing ovs-vswitch caches time spent using intel vtune.
I disabled emc lookup using "emc-insert-inv-prob=0" but still I can see emc
lookup is not disabled and also there is insertion which takes place into
emc also after the packet completes fast-path processing.
I am

Is there any other way to distinguish different types of packets/flows when
they enter dp_netdev_input__ and processed further(EMC,fastpath etc)?
As of now, I have to *flow_extract* the packets using *struct flow flow*:
if (flow.nw_proto == IPPROTO_TCP && l4_size >= TCP_HEADER_LEN) I want to
You don't need to give ip address to ovs bridge.
As you VM's are already connected through ovs-bridge, so you can simple use
iperf server on VM1 and client on another (VM2). In this case, ovs is only
working as a bridge to pass traffic from one Vm to another(as they are
already connected).

Can anyone please throw some light on this?
Waiting for a response. Thank You

Sorry , I forgot to mention I am using dpdk - 17.05 and OVS - 2.8.1
Thanks

I am using this code just before emc_processing and inside
dp_netdev_input__.
Can you please help me here?

Can you please confirm, if this is the right approach I have used and not
seeing the old values like before?

Hey Flavio
I am so sorry for the inconvenience caused.
Next time I will take care of it. You have been a great help for me.
I thank you from the bottom of my heart. I was stuck on this part since
last few days.
Now, it has been resolved.
Thanks

Statement 2 is working fine if vlogs are disabled, but I want the port
value to be stored in a variable and then print.

I am sorry, but I am trying not to use extracted flow. I want to use this
information before it goes to EMC.

Hi
Yes, you can modify the ovs code as per your requirements but before that
you need to understand and gain more knowledge about its mechanism and
study the call graphs, how the code flows. Once you understand this, it
will be easier for you.
For debugging packets, you can make use of VLOG

In my OVS-DPDK setup with VxLAN tunnel between two devices, I see the traffic stops
when I flush the ARP cache using 'ovs-appctl tnl/arp/flush'. On the packet capture, I
see the device on which I flushed the arp cache initiates the ARP request and also
receives the ARP response but it doesn't
