* (b) updates to usb_gadget to include flags "is it wireless",
* "is it wired", plus (presumably in a wrapper structure)
* bandgroup and PHY info;
* (c) presumably a wireless_ep wrapping a usb_ep, and reporting
* wireless-specific parameters like maxburst and maxsequence;
* (d) configurations that are specific to wireless links;
* (e) function drivers that understand wireless configs and will
* support wireless for (additional) function instances;
* (f) a function to support association setup (like CBAF), not
* necessarily requiring a wireless adapter;

* @setup: Used to delegate control requests that aren't handled by standard
* device infrastructure or directed at a specific interface.
* @bConfigurationValue: Copied into configuration descriptor.
* @iConfiguration: Copied into configuration descriptor.
* @bmAttributes: Copied into configuration descriptor.
* @MaxPower: Power consumtion in mA. Used to compute bMaxPower in the
* configuration descriptor after considering the bus speed.
* @cdev: assigned by @usb_add_config() before calling @bind(); this is
* the device associated with this configuration.
*
* Configurations are building blocks for gadget drivers structured around
* function drivers. Simple USB gadgets require only one function and one
* configuration, and handle dual-speed hardware by always providing the same
* functionality. Slightly more complex gadgets may have more than one
* single-function configuration at a given speed; or have configurations
* that only work at one speed.
*
* Composite devices are, by definition, ones with configurations which
* include more than one function.
*
* The lifecycle of a usb_configuration includes allocation, initialization
* of the fields described above, and calling @usb_add_config() to set up
* internal data and bind it to a specific device. The configuration's
* @bind() method is then used to initialize all the functions and then
* call @usb_add_function() for them.
*
* Those functions would normally be independent of each other, but that's
* not mandatory. CDC WMC devices are an example where functions often
* depend on other functions, with some functions subsidiary to others.
* Such interdependency may be managed in any way, so long as all of the
* descriptors complete by the time the composite driver returns from
* its bind() routine.

/**
* struct usb_function - describes one function of a configuration
* @name: For diagnostics, identifies the function.
* @strings: tables of strings, keyed by identifiers assigned during bind()
* and by language IDs provided in control requests
* @fs_descriptors: Table of full (or low) speed descriptors, using interface and
* string identifiers assigned during @bind(). If this pointer is null,
* the function will not be available at full speed (or at low speed).
* @hs_descriptors: Table of high speed descriptors, using interface and
* string identifiers assigned during @bind(). If this pointer is null,
* the function will not be available at high speed.
* @ss_descriptors: Table of super speed descriptors, using interface and
* string identifiers assigned during @bind(). If this
* pointer is null after initiation, the function will not
* be available at super speed.
* @config: assigned when @usb_add_function() is called; this is the
* configuration with which this function is associated.
* @os_desc_table: Table of (interface id, os descriptors) pairs. The function
* can expose more than one interface. If an interface is a member of
* an IAD, only the first interface of IAD has its entry in the table.
* @os_desc_n: Number of entries in os_desc_table
* @bind: Before the gadget can register, all of its functions bind() to the
* available resources including string and interface identifiers used
* in interface or class descriptors; endpoints; I/O buffers; and so on.
* @unbind: Reverses @bind; called as a side effect of unregistering the
* driver which added this function.
* @free_func: free the struct usb_function.
* @mod: (internal) points to the module that created this structure.
* @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
* initialize usb_ep.driver data at this time (when it is used).
* Note that setting an interface to its current altsetting resets
* interface state, and that all interfaces have a disabled state.
* @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.
* @resume: Notifies functions when the host restarts USB traffic.
* @get_status: Returns function status as a reply to
* GetStatus() request when the recipient is Interface.
* @func_suspend: callback to be called when
* SetFeature(FUNCTION_SUSPEND) is reseived
*
* 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.
