When we add the ability to do floating IP port forwarding with ML2/OVN, we need to update the documentation. Note that port forwarding is already available with ML2/OVS. If port forwarding was already documented for ML2/OVS, the doc impact of adding the feature to ML2/OVN might be minimal. The instructions for using port forwarding are mostly the same whether you use ML2/OVS or ML2/OVN.
