+- ``Support VF Port Representor`` (default ``not enabled``)
+
+ The i40e PF PMD supports the creation of VF port representors for the control
+ and monitoring of i40e virtual function devices. Each port representor
+ corresponds to a single virtual function of that device. Using the ``devargs``
+ option ``representor`` the user can specify which virtual functions to create
+ port representors for on initialization of the PF PMD by passing the VF IDs of
+ the VFs which are required.::
+
+ -w DBDF,representor=[0,1,4]
+
+ Currently hot-plugging of representor ports is not supported so all required
+ representors must be specified on the creation of the PF.
