Re: [ovs-discuss] TSO changes with OVS-DPDK for higher throughput
FYI, I have also created a patchsets with rebased TSO and MBuf patches on
recent master.
It also contains some fixes to tests.
Please have a look at ovs-dev mailing list:

Subject: Re: [ovs-discuss] TSO changes with OVS-DPDK for higher throughput
Hi Ian,
In May this year, through mailing list you had sent me pointers to patches to
enable Multi-Segment mbuf & TSO. Yes, the patches apply to the adb3f0b
("python: Avoid flake8 warning for unused variables.") commit. It took me some
time to figure out that DPDK 18.11.2 stable version needs to be used for this
version of OvS code.
I have just created a repository
https://github.com/harshgondaliya/ovs-dpdk-with-tso having a patched version of
OvS code and the compatible DPDK package. It includes a wiki that explains in
detail ― how to setup OvS-DPDK bridge, how to configure VMs to connect to
OvS-DPDK bridge. It will help new users like me to get started quickly with
using OvS-DPDK for Inter-VM communication.
Thanks. Regards,
Harsh Gondaliya

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=*
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=*
When using the commit as outlined above do these apply for you?

Ian

Re: [ovs-discuss] TSO changes with OVS-DPDK for higher throughput
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. Along with which version of DPDK need to use for compilation?

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.

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)

It's complete with documentation on setup and usage so should be able to
get you going.
