Hi All,
I am testing ovs-dpdk performance test with the help of IPERF.
I created VM using qemu command.
I assigned IP 10.0.1.16 to VM and other device IP is 10.0.1.18 (Dev2). I
am able to ping and able to run IPERF.
It is giving average output ~3.5G form VM to DEV2 on 10G physical
interface. form DEV2 to VM it is 5.7G throughput.
I used below version.
DPDK: dpdk-18.11.1.tar.xz
OVS: openvswitch-2.11.1
From Intel document I found TSO changes but it was for 2.6 version.
somehow I managed to apply on openvswitch-2.11.1 file.
With TSO disable I am able to do ssh other IP address of DEV2. After
enable TSO with the help of qemu command IPERF and SSH is getting hanged.

Is openvswitch-2.11.1 supports TSO enable by default?
Hi,
TSO is not available in OVS 2.11. There were patches submitted for that
release but unfortunately it did not make it upstream due to some
regression performance concerns for non TSO usecases. Intel is currently
planning to review rework the patchset to address the issues and will be
releasing a new patchset in the coming months.
In the mean time if you wish to test TSO with the previous patchset that
was available you can follow the mails and patches outlined in the
following link (it was related to a similar question)
https://mail.openvswitch.org/pipermail/ovs-discuss/2019-May/048671.html
It's complete with documentation on setup and usage so should be able to
get you going.
Regards
Ian
Is any patch availble for openvswitch-2.11.1 for TSO changes?
Is qemu related changes are required for TSO enable?
