+This profile provides the metadata required to associate a VIF with a
+:term:`VF` representor and :term:`Open vSwitch` port. If `representor_name` is

+    switches, as featured in Linux kernel 4.8 and later. This port profile can
+    currently be used with Agilio OVS networks. It is intended to be flexible
+    enough to be used by multiple vendors.
