Hi,
We are working on adding P4 support to OVS and we have recently open-sourced
the patches on the IPDK github -
https://github.com/ipdk-io/ovs/tree/ovs-with-p4
The architecture document that explains the changes and the upcoming feature
list is here -
https://github.com/ipdk-io/ovs/blob/ovs-with-p4/OVS_WITH_P4_ARCH.rst
Here is the link for the user-guide document to run OVS on host -
https://github.com/ipdk-io/ipdk/blob/main/build/ovs-with-p4_howto
We have also built a development container that ties in all necessary pieces
and runs OVS on container. It also brings up 2 Vagrant VMs and switches traffic
between them using a simple P4 and OVS -
https://github.com/ipdk-io/ipdk/blob/main/build/README.md
Here is the link to the code-walk video that we did last November -

We still have work to do to turn these patches into a minimal set that could be
upstreamed into OVS. Once that is done, we would like to upstream these
patches to openvswitch. Please let us know your comments.
Thanks
Namrata
