Rusty Russell ec3d41c4db Virtio interface 
This attempts to implement a "virtual I/O" layer which should allow
common drivers to be efficiently used across most virtual I/O
mechanisms.  It will no-doubt need further enhancement.

The virtio drivers add buffers to virtio queues; as the buffers are consumed
the driver "interrupt" callbacks are invoked.

There is also a generic implementation of config space which drivers can query
to get setup information from the host.

/**
* struct usb_device_id - identifies USB devices for probing and hotplugging
* @match_flags: Bit mask controlling of the other fields are used to match
* against new devices. Any field except for driver_info may be used,
* although some only make sense in conjunction with other fields.
* This is usually set by a USB_DEVICE_*() macro, which sets all
* other fields in this structure except for driver_info.
* @idVendor: USB vendor ID for a device; numbers are assigned
* by the USB forum to its members.
* @idProduct: Vendor-assigned product ID.
* @bcdDevice_lo: Low end of range of vendor-assigned product version numbers.
* This is also used to identify individual product versions, for
* a range consisting of a single device.
* @bcdDevice_hi: High end of version number range. The range of product
* versions is inclusive.
* @bDeviceClass: Class of device; numbers are assigned
* by the USB forum. Products may choose to implement classes,
* or be vendor-specific. Device classes specify behavior of all
* the interfaces on a devices.
* @bDeviceSubClass: Subclass of device; associated with bDeviceClass.
* @bDeviceProtocol: Protocol of device; associated with bDeviceClass.
* @bInterfaceClass: Class of interface; numbers are assigned
* by the USB forum. Products may choose to implement classes,
* or be vendor-specific. Interface classes specify behavior only
* of a given interface; other interfaces may support other classes.
* @bInterfaceSubClass: Subclass of interface; associated with bInterfaceClass.
* @bInterfaceProtocol: Protocol of interface; associated with bInterfaceClass.
* @driver_info: Holds information used by the driver. Usually it holds
* a pointer to a descriptor understood by the driver, or perhaps
* device flags.
*
* In most cases, drivers will create a table of device IDs by using
* USB_DEVICE(), or similar macros designed for that purpose.
* They will then export it to userspace using MODULE_DEVICE_TABLE(),
* and provide it to the USB core through their usb_driver structure.
*
* See the usb_match_id() function for information about how matches are
* performed. Briefly, you will normally use one of several macros to help
* construct these entries. Each entry you provide will either identify
* one or more specific products, or will identify a class of products
* which have agreed to behave the same. You should put the more specific
* matches towards the beginning of your table, so that driver_info can
* record quirks of specific products.
