Move USB network drivers to drivers/net/usb.

It is preferable to group drivers by usage (net, scsi, ATA, ...) than
by bus.  When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer
is probably less qualified on networking issues than a networking
maintainer.  Also, from a practical standpoint, chips often
appear on multiple buses, which is why we do not put drivers into
drivers/pci/net.

+	---help---
+	  This driver supports several kinds of network links over USB,
+	  with "minidrivers" built around a common network driver core
+	  that supports deep queues for efficient transfers.  (This gives
+	  better performance with small packets and at high speeds).
+
+	  The USB host runs "usbnet", and the other end of the link might be:
+
+	  - Another USB host, when using USB "network" or "data transfer"
+	    cables.  These are often used to network laptops to PCs, like
+	    "Laplink" parallel cables or some motherboards.  These rely
+	    on specialized chips from many suppliers.
+
+	  - An intelligent USB gadget, perhaps embedding a Linux system.
+	    These include PDAs running Linux (iPaq, Yopy, Zaurus, and
+	    others), and devices that interoperate using the standard
+	    CDC-Ethernet specification (including many cable modems).
+
+	  - Network adapter hardware (like those for 10/100 Ethernet) which
+	    uses this driver framework.
+
+	  The link will appear with a name like "usb0", when the link is
+	  a two-node link, or "eth0" for most CDC-Ethernet devices.  Those
+	  two-node links are most easily managed with Ethernet Bridging
+	  (CONFIG_BRIDGE) instead of routing.
+
+	  For more information see <http://www.linux-usb.org/usbnet/>.

+	  Class (CDC) Ethernet Control Model, a specification that's easy to
+	  implement in device firmware.  The CDC specifications are available
+	  from <http://www.usb.org/>.
+
+	  CDC Ethernet is an implementation option for DOCSIS cable modems
+	  that support USB connectivity, used for non-Microsoft USB hosts.
+	  The Linux-USB CDC Ethernet Gadget driver is an open implementation.
+ 	  This driver should work with at least the following devices:
+

+ 	    * Motorola (DM100 and SB4100)
+ 	    * Broadcom Cable Modem (reference design)
+ 	    * Toshiba PCX1100U
+	    * ...
+
+	  This driver creates an interface named "ethX", where X depends on
+	  what other networking devices you have in use.  However, if the
+	  IEEE 802 "local assignment" bit is set in the address, a "usbX"
+	  name is used instead.

+	  be at the root of Microsoft's "ActiveSync" too.
+
+	  Avoid using this protocol unless you have no better options.
+	  The protocol specification is incomplete, and is controlled by

+	depends on USB_USBNET
+	default y
+	help
+	  This driver module supports USB network devices that can work
+	  without any device-specific information.  Select it if you have
+	  one of these drivers.
+
+	  Note that while many USB host-to-host cables can work in this mode,
+	  that may mean not being able to talk to Win32 systems or more
+	  commonly not being able to handle certain events (like replugging
+	  the host on the other end) very well.  Also, these devices will
+	  not generally have permanently assigned Ethernet addresses.

+	help
+	  Choose this option to support the "usb-eth" networking driver
+	  used by most of the ARM Linux community with device controllers

+	  in some PXA versions of the "blob" boot loader.
+
+	  Linux-based "Gumstix" PXA-25x based systems use this protocol
+	  to talk with other Linux systems.
+
+	  Although the ROMs shipped with Sharp Zaurus products use a
+	  different link level framing protocol, you can have them use
+	  this simpler protocol by installing a different kernel.
+
+config USB_EPSON2888
+	boolean "Epson 2888 based firmware (DEVELOPMENT)"
+	depends on USB_NET_CDC_SUBSET
+	help
+	  Choose this option to support the usb networking links used

+	depends on USB_NET_CDC_SUBSET && EXPERIMENTAL
+	help
+	  Choose this option if you're using a host-to-host cable

+	tristate "Sharp Zaurus (stock ROMs) and compatible"
+	depends on USB_USBNET
+	select USB_NET_CDCETHER
+	select CRC32
+	default y
+	help
+	  Choose this option to support the usb networking links used by
+	  Zaurus models like the SL-5000D, SL-5500, SL-5600, A-300, B-500.
+	  This also supports some related device firmware, as used in some
+	  PDAs from Olympus and some cell phones from Motorola.
+
+	  If you install an alternate image, such as the Linux 2.6 based
+	  versions of OpenZaurus, you should no longer need to support this
+	  protocol.  Only the "eth-fd" or "net_fd" drivers in these devices
+	  really need this non-conformant variant of CDC Ethernet (or in
+	  some cases CDC MDLM) protocol, not "g_ether".

+/*
+ * This supports simple USB network links that don't require any special
+ * framing or hardware control operations.  The protocol used here is a
+ * strict subset of CDC Ethernet, with three basic differences reflecting
+ * the goal that almost any hardware should run it:
+ *
+ *  - Minimal runtime control:  one interface, no altsettings, and
+ *    no vendor or class specific control requests.  If a device is
+ *    configured, it is allowed to exchange packets with the host.
+ *    Fancier models would mean not working on some hardware.
+ *
+ *  - Minimal manufacturing control:  no IEEE "Organizationally
+ *    Unique ID" required, or an EEPROMs to store one.  Each host uses
+ *    one random "locally assigned" Ethernet address instead, which can
+ *    of course be overridden using standard tools like "ifconfig".
+ *    (With 2^46 such addresses, same-net collisions are quite rare.)
+ *
+ *  - There is no additional framing data for USB.  Packets are written
+ *    exactly as in CDC Ethernet, starting with an Ethernet header and
+ *    terminated by a short packet.  However, the host will never send a
+ *    zero length packet; some systems can't handle those robustly.
+ *
+ * Anything that can transmit and receive USB bulk packets can implement
+ * this protocol.  That includes both smart peripherals and quite a lot
+ * of "host-to-host" USB cables (which embed two devices back-to-back).
+ *
+ * Note that although Linux may use many of those host-to-host links
+ * with this "cdc_subset" framing, that doesn't mean there may not be a
+ * better approach.  Handling the "other end unplugs/replugs" scenario
+ * well tends to require chip-specific vendor requests.  Also, Windows
+ * peers at the other end of host-to-host cables may expect their own
+ * framing to be used rather than this "cdc_subset" model.

+ * The GeneSys docs imply there's some NDIS issue motivating this framing.
+ *
+ * Some info from GeneSys:
+ *  - GL620USB-A is full duplex; GL620USB is only half duplex for bulk.
+ *    (Some cables, like the BAFO-100c, use the half duplex version.)
+ *  - For the full duplex model, the low bit of the version code says
+ *    which side is which ("left/right").
+ *  - For the half duplex type, a control/interrupt handshake settles
+ *    the transfer direction.  (That's disabled here, partially coded.)
+ *    A control URB would block until other side writes an interrupt.
+ *
+ * Original code from Jiun-Jie Huang <huangjj@genesyslogic.com.tw>

+ *	ChangeLog:
+ *		....	Most of the time spent on reading sources & docs.
+ *		v0.2.x	First official release for the Linux kernel.
+ *		v0.3.0	Beutified and structured, some bugs fixed.
+ *		v0.3.x	URBifying bulk requests and bugfixing. First relatively
+ *			stable release. Still can touch device's registers only
+ *			from top-halves.
+ *		v0.4.0	Control messages remained unurbified are now URBs.
+ *			Now we can touch the HW at any time.
+ *		v0.4.9	Control urbs again use process context to wait. Argh...
+ *			Some long standing bugs (enable_net_traffic) fixed.
+ *			Also nasty trick about resubmiting control urb from
+ *			interrupt context used. Please let me know how it
+ *			behaves. Pegasus II support added since this version.
+ *			TODO: suppressing HCD warnings spewage on disconnect.
+ *		v0.4.13	Ethernet address is now set at probe(), not at open()
+ *			time as this seems to break dhcpd. 
+ *		v0.5.0	branch to 2.5.x kernels
+ *		v0.5.1	ethtool support added
+ *		v0.5.5	rx socket buffers are in a pool and the their allocation
+ * 			is out of the interrupt routine.

+ *
+ * NOTE that Microsoft's "RNDIS 1.0" specification is incomplete.  Issues
+ * include:
+ *    - Power management in particular relies on information that's scattered
+ *	through other documentation, and which is incomplete or incorrect even
+ *	there.
+ *    - There are various undocumented protocol requirements, such as the
+ *	need to send unused garbage in control-OUT messages.
+ *    - In some cases, MS-Windows will emit undocumented requests; this
+ *	matters more to peripheral implementations than host ones.
+ *
+ * Moreover there's a no-open-specs variant of RNDIS called "ActiveSync".
+ *
+ * For these reasons and others, ** USE OF RNDIS IS STRONGLY DISCOURAGED ** in
+ * favor of such non-proprietary alternatives as CDC Ethernet or the newer (and
+ * currently rare) "Ethernet Emulation Model" (EEM).
