+ * in place.
+ * @exit: Deinitialize the cryptographic transformation object. This is a
+ * counterpart to @init, used to remove various changes set in
+ * @init.
+ * @ivsize: IV size applicable for transformation. The consumer must provide an
+ * IV of exactly that size to perform the encrypt or decrypt operation.
+ * @chunksize: Equal to the block size except for stream ciphers such as

+ * messages.
+ * @flags: Set to 0.
+ * @msg: The message payload.
+ * @reply: This field is ignored with CEC_RECEIVE and is only used by
+ * CEC_TRANSMIT. If non-zero, then wait for a reply with this
+ * opcode. Set to CEC_MSG_FEATURE_ABORT if you want to wait for
+ * a possible ABORT reply. If there was an error when sending the
+ * msg or FeatureAbort was returned, then reply is set to 0.

- *
- * This tells the device controller to perform the specified request through
- * that endpoint (reading or writing a buffer). When the request completes,
- * including being canceled by usb_ep_dequeue(), the request's completion
- * routine is called to return the request to the driver. Any endpoint
- * (except control endpoints like ep0) may have more than one transfer
- * request queued; they complete in FIFO order. Once a gadget driver
- * submits a request, that request may not be examined or modified until it
- * is given back to that driver through the completion callback.
- *
- * Each request is turned into one or more packets. The controller driver
- * never merges adjacent requests into the same packet. OUT transfers
- * will sometimes use data that's already buffered in the hardware.
- * Drivers can rely on the fact that the first byte of the request's buffer
- * always corresponds to the first byte of some USB packet, for both
- * IN and OUT transfers.
- *
- * Bulk endpoints can queue any amount of data; the transfer is packetized
- * automatically. The last packet will be short if the request doesn't fill it
- * out completely. Zero length packets (ZLPs) should be avoided in portable
- * protocols since not all usb hardware can successfully handle zero length
- * packets. (ZLPs may be explicitly written, and may be implicitly written if
- * the request 'zero' flag is set.) Bulk endpoints may also be used
- * for interrupt transfers; but the reverse is not true, and some endpoints
- * won't support every interrupt transfer. (Such as 768 byte packets.)
- *
- * Interrupt-only endpoints are less functional than bulk endpoints, for
- * example by not supporting queueing or not handling buffers that are
- * larger than the endpoint's maxpacket size. They may also treat data
- * toggle differently.
- *
- * Control endpoints ... after getting a setup() callback, the driver queues
- * one response (even if it would be zero length). That enables the
- * status ack, after transferring data as specified in the response. Setup
- * functions may return negative error codes to generate protocol stalls.
- * (Note that some USB device controllers disallow protocol stall responses
- * in some cases.) When control responses are deferred (the response is
- * written after the setup callback returns), then usb_ep_set_halt() may be
- * used on ep0 to trigger protocol stalls. Depending on the controller,
- * it may not be possible to trigger a status-stage protocol stall when the
- * data stage is over, that is, from within the response's completion
- * routine.
- *
- * For periodic endpoints, like interrupt or isochronous ones, the usb host
- * arranges to poll once per interval, and the gadget driver usually will
- * have queued some data to transfer at that time.

-/**
- * DOC: Media Controller
- *
- * The media controller userspace API is documented in DocBook format in
- * Documentation/DocBook/media/v4l/media-controller.xml. This document focus
- * on the kernel-side implementation of the media framework.
- *
- * * Abstract media device model:
- *
- * Discovering a device internal topology, and configuring it at runtime, is one
- * of the goals of the media framework. To achieve this, hardware devices are
- * modelled as an oriented graph of building blocks called entities connected
- * through pads.
- *
- * An entity is a basic media hardware building block. It can correspond to
- * a large variety of logical blocks such as physical hardware devices
- * (CMOS sensor for instance), logical hardware devices (a building block
- * in a System-on-Chip image processing pipeline), DMA channels or physical
- * connectors.
- *
- * A pad is a connection endpoint through which an entity can interact with
- * other entities. Data (not restricted to video) produced by an entity
- * flows from the entity's output to one or more entity inputs. Pads should
- * not be confused with physical pins at chip boundaries.
- *
- * A link is a point-to-point oriented connection between two pads, either
- * on the same entity or on different entities. Data flows from a source
- * pad to a sink pad.
- *
- *
- * * Media device:
- *
- * A media device is represented by a struct &media_device instance, defined in
- * include/media/media-device.h. Allocation of the structure is handled by the
- * media device driver, usually by embedding the &media_device instance in a
- * larger driver-specific structure.
- *
- * Drivers register media device instances by calling
- * __media_device_register() via the macro media_device_register()
- * and unregistered by calling
- * media_device_unregister().
- *
- * * Entities, pads and links:
- *
- * - Entities
- *
- * Entities are represented by a struct &media_entity instance, defined in
- * include/media/media-entity.h. The structure is usually embedded into a
- * higher-level structure, such as a v4l2_subdev or video_device instance,
- * although drivers can allocate entities directly.
- *
- * Drivers initialize entity pads by calling
- * media_entity_pads_init().
- *
- * Drivers register entities with a media device by calling
- * media_device_register_entity()
- * and unregistred by calling
- * media_device_unregister_entity().
- *
- * - Interfaces
- *
- * Interfaces are represented by a struct &media_interface instance, defined in
- * include/media/media-entity.h. Currently, only one type of interface is
- * defined: a device node. Such interfaces are represented by a struct
- * &media_intf_devnode.
- *
- * Drivers initialize and create device node interfaces by calling
- * media_devnode_create()
- * and remove them by calling:
- * media_devnode_remove().
- *
- * - Pads
- *
- * Pads are represented by a struct &media_pad instance, defined in
- * include/media/media-entity.h. Each entity stores its pads in a pads array
- * managed by the entity driver. Drivers usually embed the array in a
- * driver-specific structure.
- *
- * Pads are identified by their entity and their 0-based index in the pads
- * array.
- * Both information are stored in the &media_pad structure, making the
- * &media_pad pointer the canonical way to store and pass link references.
- *
- * Pads have flags that describe the pad capabilities and state.
- *
- * %MEDIA_PAD_FL_SINK indicates that the pad supports sinking data.
- * %MEDIA_PAD_FL_SOURCE indicates that the pad supports sourcing data.
- *
- * NOTE: One and only one of %MEDIA_PAD_FL_SINK and %MEDIA_PAD_FL_SOURCE must
- * be set for each pad.
- *
- * - Links
- *
- * Links are represented by a struct &media_link instance, defined in
- * include/media/media-entity.h. There are two types of links:
- *
- * 1. pad to pad links:
- *
- * Associate two entities via their PADs. Each entity has a list that points
- * to all links originating at or targeting any of its pads.
- * A given link is thus stored twice, once in the source entity and once in
- * the target entity.
- *
- * Drivers create pad to pad links by calling:
- * media_create_pad_link() and remove with media_entity_remove_links().
- *
- * 2. interface to entity links:
- *
- * Associate one interface to a Link.
- *
- * Drivers create interface to entity links by calling:
- * media_create_intf_link() and remove with media_remove_intf_links().
- *
- * NOTE:
- *
- * Links can only be created after having both ends already created.
- *
- * Links have flags that describe the link capabilities and state. The
- * valid values are described at media_create_pad_link() and
- * media_create_intf_link().
- *
- * Graph traversal:
- *
- * The media framework provides APIs to iterate over entities in a graph.
- *
- * To iterate over all entities belonging to a media device, drivers can use
- * the media_device_for_each_entity macro, defined in
- * include/media/media-device.h.
- *
- * struct media_entity *entity;
- *
- * media_device_for_each_entity(entity, mdev) {
- * // entity will point to each entity in turn
- * ...
- * }
- *
- * Drivers might also need to iterate over all entities in a graph that can be
- * reached only through enabled links starting at a given entity. The media
- * framework provides a depth-first graph traversal API for that purpose.
- *
- * Note that graphs with cycles (whether directed or undirected) are *NOT*
- * supported by the graph traversal API. To prevent infinite loops, the graph
- * traversal code limits the maximum depth to MEDIA_ENTITY_ENUM_MAX_DEPTH,
- * currently defined as 16.
- *
- * Drivers initiate a graph traversal by calling
- * media_entity_graph_walk_start()
- *
- * The graph structure, provided by the caller, is initialized to start graph
- * traversal at the given entity.
- *
- * Drivers can then retrieve the next entity by calling
- * media_entity_graph_walk_next()
- *
- * When the graph traversal is complete the function will return NULL.
- *
- * Graph traversal can be interrupted at any moment. No cleanup function call
- * is required and the graph structure can be freed normally.
- *
- * Helper functions can be used to find a link between two given pads, or a pad
- * connected to another pad through an enabled link
- * media_entity_find_link() and media_entity_remote_pad()
- *
- * Use count and power handling:
- *
- * Due to the wide differences between drivers regarding power management
- * needs, the media controller does not implement power management. However,
- * the &media_entity structure includes a use_count field that media drivers
- * can use to track the number of users of every entity for power management
- * needs.
- *
- * The &media_entity.@use_count field is owned by media drivers and must not be
- * touched by entity drivers. Access to the field must be protected by the
- * &media_device.@graph_mutex lock.
- *
- * Links setup:
- *
- * Link properties can be modified at runtime by calling
- * media_entity_setup_link()
- *
- * Pipelines and media streams:
- *
- * When starting streaming, drivers must notify all entities in the pipeline to
- * prevent link states from being modified during streaming by calling
- * media_entity_pipeline_start().
- *
- * The function will mark all entities connected to the given entity through
- * enabled links, either directly or indirectly, as streaming.
- *
- * The &media_pipeline instance pointed to by the pipe argument will be stored
- * in every entity in the pipeline. Drivers should embed the &media_pipeline
- * structure in higher-level pipeline structures and can then access the
- * pipeline through the &media_entity pipe field.
- *
- * Calls to media_entity_pipeline_start() can be nested. The pipeline pointer
- * must be identical for all nested calls to the function.
- *
- * media_entity_pipeline_start() may return an error. In that case, it will
- * clean up any of the changes it did by itself.
- *
- * When stopping the stream, drivers must notify the entities with
- * media_entity_pipeline_stop().
- *
- * If multiple calls to media_entity_pipeline_start() have been made the same
- * number of media_entity_pipeline_stop() calls are required to stop streaming.
- * The &media_entity pipe field is reset to NULL on the last nested stop call.
- *
- * Link configuration will fail with -%EBUSY by default if either end of the
- * link is a streaming entity. Links that can be modified while streaming must
- * be marked with the %MEDIA_LNK_FL_DYNAMIC flag.
- *
- * If other operations need to be disallowed on streaming entities (such as
- * changing entities configuration parameters) drivers can explicitly check the
- * media_entity stream_count field to find out if an entity is streaming. This
- * operation must be done with the media_device graph_mutex held.
- *
- * Link validation:
- *
- * Link validation is performed by media_entity_pipeline_start() for any
- * entity which has sink pads in the pipeline. The
- * &media_entity.@link_validate() callback is used for that purpose. In
- * @link_validate() callback, entity driver should check that the properties of
- * the source pad of the connected entity and its own sink pad match. It is up
- * to the type of the entity (and in the end, the properties of the hardware)
- * what matching actually means.
- *
- * Subsystems should facilitate link validation by providing subsystem specific
- * helper functions to provide easy access for commonly needed information, and
- * in the end provide a way to use driver-specific callbacks.

+ * struct ndisc_options *ndopts):
+ * This function is called while parsing ndisc ops and put each position
+ * as pointer into ndopts. If this function return unequal 0, then this

+ * option parser will take care about that option.
+ *
+ * void (*update)(const struct net_device *dev, struct neighbour *n,
+ * u32 flags, u8 icmp6_type,
+ * const struct ndisc_options *ndopts):
+ * This function is called when IPv6 ndisc updates the neighbour cache

+ *
+ * int (*opt_addr_space)(const struct net_device *dev, u8 icmp6_type,
+ * struct neighbour *neigh, u8 *ha_buf,
+ * u8 **ha):
+ * This function is called when the necessary option space will be

+ *
+ * void (*fill_addr_option)(const struct net_device *dev,
+ * struct sk_buff *skb, u8 icmp6_type,
+ * const u8 *ha):
+ * This function is called when the skb will finally fill the option
