Hi all !

I noticed that the current OvS userspace TSO implementation supports flat and VLAN networks only. I want to know is there any plan to support userspace TSO over tunnel?

@wangjun0728 Thanks, but it seems the patch has not been updated for almost 2 years.

It can only be used as a reference. I also recently checked whether this patch can be applied on the new version.

Hi. There is ongoing work for improving checksum offload capabilities (waiting for v10, changes requested a few weeks ago): https://patchwork.ozlabs.org/project/openvswitch/list/?series=329844&state=* It is part of larger TSO support improvement (waiting for checksum patches to go in before continuing this work): https://patchwork.ozlabs.org/project/openvswitch/list/?series=307485&state=*
