Yes. It is configured through the OVS database using the QoS and Queue

ovs-openflowd does not support queue configuration. You have to use
OVS does not support OFPT_QUEUE_GET_CONFIG_REQUEST. It would not help
anyway, because OpenFlow only defines one queue property which doesn't
include enough information to accurately specify any of the forms of QoS
that OVS supports.
You should not expect to use OpenFlow to configure queues anyway, since
OpenFlow 1.0 says, in section 5.3.4: "Queue configuration takes place
outside the OpenFlow protocol, either through a command line tool or
through an external dedicated configuration protocol."
