Comment 2 for bug 1843165

yes,

So today ovs mechanism driver can bind Direct port see [1] for ovs offload.
ovs was extended with tc-offload to support rate limit see [1].
The ovs qos drive [2] it limited to work only with Normal Ports, so we can't put QOS rules on direct port.
We just want to add Direct port to ovs Qos driver as done here [4]
