+
+        We handle the the backend driver part with allowing network_plugin to

+        whatever knows when we are hooking up an Ironic node so it can pass
+        along that key during port_create().
+
+        IPAM is a little trickier, especially in Ironic's case, because we
+        *must* use a specific IPAM for provider networks. There isn't really
+        much of an option other than involve the backend driver when selecting
