* @type: %OVS_VPORT_TYPE_* value for this type of virtual port.
- * @flags: Flags of type VPORT_F_* that influence how the generic vport layer
- * handles this vport.
- * @init: Called at module initialization. If VPORT_F_REQUIRED is set then the
- * failure of this function will cause the module to not load. If the flag is
- * not set and initialzation fails then no vports of this type can be created.
- * @exit: Called at module unload.
* @create: Create a new vport configured as specified. On success returns
* a new vport allocated with ovs_vport_alloc(), otherwise an ERR_PTR() value.
* @destroy: Destroys a vport. Must call vport_free() on the vport but not
* existing vport to a &struct sk_buff. May be %NULL for a vport that does not
* have any configuration.
* @get_name: Get the device's name.
- * @get_config: Get the device's configuration.
- * May be null if the device does not have an ifindex.
- * @send: Send a packet on the device. Returns the length of the packet sent.
+ * @send: Send a packet on the device. Returns the length of the packet sent,
+ * zero for dropped packets or negative for error.
