STP is only available via REST-API, see
http://ovirt.github.io/ovirt-engine-api-model/4.3/#types/network
please find an example how to enable STP in
https://gist.github.com/dominikholler/4e70c9ef9929d93b6807f56d43a70b95
We have no plans to add STP to the web ui,
but new feature requests are always welcome on
