Hi, I am using OVN with openstack neutron on ubuntu 20.04. I want to enable hardware offloading on ovs. I have used below command to to enable offload.
ovs-vsctl set Open_vSwitch . other_config:hw-offload=true By reviewing below URL. https://www.openvswitch.org/support/ovscon2019/day2/0951-hw_offload_ovs_con_19-Oz-Mellanox.pdf I just want to enable kernel offload using tc.
