<p class="MsoNormal">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.<o:p></o:p></p>

<p class="MsoNormal">I have just created a repository <a href="https://github.com/harshgondaliya/ovs-dpdk-with-tso">https://github.com/harshgondaliya/ovs-dpdk-with-tso</a> having a patched version of OvS code and the compatible DPDK package. It includes a
wiki that explains in detail <span style="font-size:10.5pt;font-family:"Arial",sans-serif">― </span>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

Hi Murali,<br>
<br>
the commit these patches can be applied to are listed in the cover <br>
letter for the patchsets.<br>
<br>
I believe you want to check out the following commit from the ovs master <br>
branch (this commit was pre 2.11 release)<br>
<br>
adb3f0b ("python: Avoid flake8 warning for unused variables.")<br>
<br>
You should then be able to apply the mutliseg patchset on top of this <br>
commit (Multiseg is a pre-requirement for enabling TSO, see link below)<br>
<br>
<a href="https://patchwork.ozlabs.org/project/openvswitch/list/?series=85802&state=*" target="_blank">https://patchwork.ozlabs.org/project/openvswitch/list/?series=85802&state=*</a><br>
<br>
Once these are applied you should be able to apply the TSO enablement <br>
patchset then (see link below).<br>
<br>
<a href="https://patchwork.ozlabs.org/project/openvswitch/list/?series=85807&state=*" target="_blank">https://patchwork.ozlabs.org/project/openvswitch/list/?series=85807&state=*</a><br>
<br>
When using the commit as outlined above do these apply for you?<br>
<br>
