Thank Ian Stokes,
It is very helpful for us. I was trying to apply these patches on
openvswitch-2.11.1 repository, it was failing.
Some of the files are not found.
Could you, please let me know suitable version of ovs, where these
patches will get apply successfully.
Hi Murali,
the commit these patches can be applied to are listed in the cover
letter for the patchsets.
I believe you want to check out the following commit from the ovs master
branch (this commit was pre 2.11 release)
adb3f0b ("python: Avoid flake8 warning for unused variables.")
You should then be able to apply the mutliseg patchset on top of this
commit (Multiseg is a pre-requirement for enabling TSO, see link below)
https://patchwork.ozlabs.org/project/openvswitch/list/?series=85802&state=*
Once these are applied you should be able to apply the TSO enablement
patchset then (see link below).
https://patchwork.ozlabs.org/project/openvswitch/list/?series=85807&state=*
When using the commit as outlined above do these apply for you?
Regards
Ian
Along with which version of DPDK need to use for compilation?

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
