Bug Description

I am running Focal 20.04 with Openstack OVN and trying to setup dpdk support for high performance networking but i am not lucky, As soon as i spin up VM its getting setup and start pinging and which in few second OVS switch crashed and restarted. I try to reach out some folks in IRC for openvswitch support and they said it might be issue of TSO and they said patch is out there but may be not include in distribution package.

Patch:<email address hidden>/

My openvswitch version is following

root@ovn-lab-comp-dpdk-1:~# dpkg -l | grep openvswitch
ii openvswitch-common 2.13.3-0ubuntu0.20.04.2 amd64 Open vSwitch common components
ii openvswitch-switch 2.13.3-0ubuntu0.20.04.2 amd64 Open vSwitch switch implementations
ii openvswitch-switch-dpdk 2.13.3-0ubuntu0.20.04.2 amd64 DPDK enabled Open vSwitch switch implementation
ii python3-openvswitch 2.13.3-0ubuntu0.20.04.2 all Python 3 bindings for Open vSwitch

Does anyone hit this kind of issue where openvswitch keep crashing and rebooting (interesting this it doesn't created crash dump so not sure where to look and what to look?)
