/*
|
||||
* Ethernet gadget driver -- with CDC and non-CDC options
|
||||
* Builds on hardware support for a full duplex link.
|
||||
*
|
||||
* CDC Ethernet is the standard USB solution for sending Ethernet frames
|
||||
* using USB. Real hardware tends to use the same framing protocol but look
|
||||
* different for control features. This driver strongly prefers to use
|
||||
* this USB-IF standard as its open-systems interoperability solution;
|
||||
* most host side USB stacks (except from Microsoft) support it.
|
||||
*
|
||||
* There's some hardware that can't talk CDC. We make that hardware
|
||||
* implement a "minimalist" vendor-agnostic CDC core: same framing, but
|
||||
* link-level setup only requires activating the configuration.
|
||||
* Linux supports it, but other host operating systems may not.
|
||||
* (This is a subset of CDC Ethernet.)
|
||||
*
|
||||
* A third option is also in use. Rather than CDC Ethernet, or something
|
||||
* simpler, Microsoft pushes their own approach: RNDIS. The published
|
||||
* RNDIS specs are ambiguous and appear to be incomplete, and are also
|
||||
* needlessly complex.

* initialize usb_ep.driver data at this time (when it is used).

|
||||
* @get_alt: Returns the active altsetting. If this is not provided,
|
||||
* then only altsetting zero is supported.
|
||||
* @disable: (REQUIRED) Indicates the function should be disabled. Reasons
|
||||
* include host resetting or reconfiguring the gadget, and disconnection.
|
||||
* @setup: Used for interface-specific control requests.
|
||||
* @suspend: Notifies functions when the host stops sending USB traffic.

|

*
|
||||
* A single USB function uses one or more interfaces, and should in most
|
||||
* cases support operation at both full and high speeds. Each function is
|
||||
* associated by @usb_add_function() with a one configuration; that function
|
||||
* causes @bind() to be called so resources can be allocated as part of
|
||||
* setting up a gadget driver. Those resources include endpoints, which
|
||||
* should be allocated using @usb_ep_autoconfig().
|
||||
*
|
||||
* To support dual speed operation, a function driver provides descriptors
|
||||
* for both high and full speed operation. Except in rare cases that don't
|
||||
* involve bulk endpoints, each speed needs different endpoint descriptors.
|
||||
*
|
||||
* Function drivers choose their own strategies for managing instance data.
|
||||
* The simplest strategy just declares it "static', which means the function
|
||||
* can only be activated once. If the function needs to be exposed in more
|
||||
* than one configuration at a given speed, it needs to support multiple
|
||||
* usb_function structures (one for each configuration).
|
||||
*
|
||||
* A more complex strategy might encapsulate a @usb_function structure inside
|
||||
* a driver-specific instance structure to allows multiple activations. An
|
||||
* example of multiple activations might be a CDC ACM function that supports
|
||||
* two or more distinct instances within the same configuration, providing
|
||||
* several independent logical data links to a USB host.

/* Driver for USB Mass Storage compliant devices
|
||||
* Transport Functions Header File
|
||||
*
|
||||
* Current development and maintenance by:
|
||||
* (c) 1999, 2000 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
|
||||
*
|
||||
* This driver is based on the 'USB Mass Storage Class' document. This
|
||||
* describes in detail the protocol used to communicate with such
|
||||
* devices. Clearly, the designers had SCSI and ATAPI commands in
|
||||
* mind when they created this document. The commands are all very
|
||||
* similar to commands in the SCSI-II and ATAPI specifications.
|
||||
*
|
||||
* It is important to note that in a number of cases this class
|
||||
* exhibits class-specific exemptions from the USB specification.
|
||||
* Notably the usage of NAK, STALL and ACK differs from the norm, in
|
||||
* that they are used to communicate wait, failed and OK on commands.
|
||||
*
|
||||
* Also, for certain devices, the interrupt endpoint is used to convey
|
||||
* status of a command.
|
||||
*
|
||||
* Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
|
||||
* information about this driver.
