Currently Midokura uses its own script (mm-ctl) to bind ports. However, support for using this script is left out of the nova and neutron projects. This causes confusion and makes deployments unnecessarily complicated for customers using Havana. This fix is to change Neutron to properly set up port bindings to use the "midonet" vif driver when creating a port. Corresponding changes will be submitted to the devstack and Nova projects.
