Doc Type:	Known Issue
Doc Text:	Currently, in ML2/OVS deployments, Open vSwitch (OVS) does not support offloading OpenFlow rules that have the `skb_priority`, `skb_mark`, or output queue fields set. These fields are required for Quality of Service (QoS) support for virtio ports. + If you set a minimum bandwidth rule for a virtio port, the Networking service (neutron) OVS agent marks the traffic of this port with a Packet Mark field. This traffic cannot be offloaded, and it affects the traffic in other ports. If you set a bandwidth limit rule, all traffic is marked with the default 0 queue, which means that no traffic can be offloaded. + Workaround: If your environment includes OVS hardware offload ports, disable packet marking in the nodes that require hardware offloading. When you disable packet marking, it is not possible to set rate limiting rules for virtio ports. However, differentiated services code point (DSCP) marking rules are still available. + In the configuration file, set the `disable_packet_marking` flag to `true`. When you edit the configuration file, you must restart the `neutron_ovs_agent` container. For example: + ---- $ cat `/var/lib/config-data/puppet-generated/neutron/etc/neutron/plugins/ml2/openvswitch_agent.ini` [ovs] disable_packet_marking=True ----

Description Miguel Angel Nieto 2022-07-22 15:50:26 UTC

Description of problem:
Traffic is not offloaded when in a ml2-ovs environment. It is not offloaded any kind of traffic (udp, tcp, icmp) and any kind of network (vxlan/vlan)

I will provide information here for the udp traffic using a vlan provider network.

Version-Release number of selected component (if applicable):
RHOS-17.0-RHEL-9-20220701.n.1
openvswitch2.17-2.17.0-10.el9fdp.x86_64


How reproducible:
Deploy 17.0 ml2-ovs hwoffload templates (i will attach them)
Run Testcase nfv_tempest_plugin.tests.scenario.test_nfv_offload.TestNfvOffload.test_offload_udp
The testcase do the following steps:
1. create 2 vms
2. execute tcpdump in representor port
3. execute iperf in vms
4. checks:
   - for each flow there should be 1 packet in representor port



Actual results:
Traffic is not offloaded


Expected results:
Traffic should be offloaded
