The first hint using the new ``hints`` port attribute is the
``ovs-tx-steering`` hint. The availability of this is marked
by the extension: ``port-hint-ovs-tx-steering``. This hint is
specific to the ``openvswitch`` mechanism driver. It enables
the control of Open vSwitch's Userspace Tx packet steering
feature. For details about the Open vSwitch feature please see:
https://docs.openvswitch.org/en/latest/topics/userspace-tx-steering/
The valid values for the ``hints`` attribute introduced by the 2nd
extension are:
``{"openvswitch": {"other_config": {"tx-steering": "hash|thread"}}}``
