+/**
+ * enum ovs_vport_attr - attributes for %OVS_VPORT_* commands.
+ * @OVS_VPORT_ATTR_PORT_NO: 32-bit port number within datapath.
+ * @OVS_VPORT_ATTR_TYPE: 32-bit %OVS_VPORT_TYPE_* constant describing the type
+ * of vport.
+ * @OVS_VPORT_ATTR_NAME: Name of vport. For a vport based on a network device
+ * this is the name of the network device. Maximum length %IFNAMSIZ-1 bytes
+ * plus a null terminator.
+ * @OVS_VPORT_ATTR_UPCALL_PID: The Netlink socket in userspace that
+ * OVS_PACKET_CMD_MISS upcalls will be directed to for packets received on
+ * this port. A value of zero indicates that upcalls should not be sent.
+ * @OVS_VPORT_ATTR_STATS: A &struct ovs_vport_stats giving statistics for
+ * packets sent or received through the vport.
+ * @OVS_VPORT_ATTR_ADDRESS: A 6-byte Ethernet address for the vport.
+ * @OVS_VPORT_ATTR_IFINDEX: ifindex of the underlying network device, if any.
+ *
+ * These attributes follow the &struct ovs_header within the Generic Netlink
+ * payload for %OVS_VPORT_* commands.
+ *
+ * All attributes applicable to a given port are present in notifications.
+ * This means that, for example, a vport that has no corresponding network
+ * device would omit %OVS_VPORT_ATTR_IFINDEX.
+ *
+ * For %OVS_VPORT_CMD_NEW requests, the %OVS_VPORT_ATTR_TYPE and
+ * %OVS_VPORT_ATTR_NAME attributes are required. %OVS_VPORT_ATTR_PORT_NO is
+ * optional; if not specified a free port number is automatically selected.
+ * Whether %OVS_VPORT_ATTR_OPTIONS is required or optional depends on the type
+ * of vport. %OVS_VPORT_ATTR_STATS and %OVS_VPORT_ATTR_ADDRESS are optional,
+ * and other attributes are ignored.
+ *
+ * For other requests, if %OVS_VPORT_ATTR_NAME is specified then it is used to
+ * look up the vport to operate on; otherwise dp_idx from the &struct
+ * ovs_header plus %OVS_VPORT_ATTR_PORT_NO determine the vport.
