-    * The new in_phy_port field in OFPT_PACKET_IN needs some kind of
-      implementation.  It has a sensible interpretation for tunnels
-      but in general the physical port is not in the datapath for OVS
-      so the value is not necessarily meaningful.  We might have to
-      just fix it as the same as in_port.

     * OFPT_TABLE_MOD message.  This is new in OF1.1, so we need to
       implement it.  It should be implemented so that the default OVS
       behavior does not change.
