+/*
+ * 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.

+ * GeneSys GL620USB-A (www.genesyslogic.com.tw)
+ *
+ * ... should partially interop with the Win32 driver for this hardware.
+ * 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>
+ * and merged into "usbnet" by Stanislav Brabec <utx@penguin.cz>.

 /*
  * This is a generic "USB networking" framework that works with several
- * kinds of full and high speed networking devices:
- *
- *   + USB host-to-host "network cables", used for IP-over-USB links.
- *     These are often used for Laplink style connectivity products.
- *      - AnchorChip 2720
- *      - Belkin, eTEK (interops with Win32 drivers)
- *      - GeneSys GL620USB-A
- *      - NetChip 1080 (interoperates with NetChip Win32 drivers)
- *      - Prolific PL-2301/2302 (replaces "plusb" driver)
- *      - KC Technology KC2190
- *
- *   + Smart USB devices can support such links directly, using Internet
- *     standard protocols instead of proprietary host-to-device links.
- *      - Linux PDAs like iPaq, Yopy, and Zaurus
- *      - The BLOB boot loader (for diskless booting)
- *      - Linux "gadgets", perhaps using PXA-2xx or Net2280 controllers
- *      - Devices using EPSON's sample USB firmware
- *      - CDC-Ethernet class devices, such as many cable modems
- *
- *   + Adapters to networks such as Ethernet.
- *      - AX8817X based USB 2.0 products
- *
- * Links to these devices can be bridged using Linux Ethernet bridging.
- * With minor exceptions, these all use similar USB framing for network
- * traffic, but need different protocols for control traffic.
- *
- * USB devices can implement their side of this protocol at the cost
- * of two bulk endpoints; it's not restricted to "cable" applications.
- * See the SA1110, Zaurus, or EPSON device/client support in this driver;
- * slave/target drivers such as "usb-eth" (on most SA-1100 PDAs) or
- * "g_ether" (in the Linux "gadget" framework) implement that behavior
- * within devices.
- *
- *
- * CHANGELOG:
- *
- * 13-sep-2000  experimental, new
- * 10-oct-2000  usb_device_id table created. 
- * 28-oct-2000  misc fixes; mostly, discard more TTL-mangled rx packets.
- * 01-nov-2000  usb_device_id table and probing api update by
- *              Adam J. Richter <adam@yggdrasil.com>.
- * 18-dec-2000  (db) tx watchdog, "net1080" renaming to "usbnet", device_info
- *              and prolific support, isolate net1080-specific bits, cleanup.
- *              fix unlink_urbs oops in D3 PM resume code path.
- *
- * 02-feb-2001  (db) fix tx skb sharing, packet length, match_flags, ...
- * 08-feb-2001  stubbed in "linuxdev", maybe the SA-1100 folk can use it;
- *              AnchorChips 2720 support (from spec) for testing;
- *              fix bit-ordering problem with ethernet multicast addr
- * 19-feb-2001  Support for clearing halt conditions. SA1100 UDC support
- *              updates. Oleg Drokin (green@iXcelerator.com)
- * 25-mar-2001  More SA-1100 updates, including workaround for ip problem
- *              expecting cleared skb->cb and framing change to match latest
- *              handhelds.org version (Oleg).  Enable device IDs from the
- *              Win32 Belkin driver; other cleanups (db).
- * 16-jul-2001  Bugfixes for uhci oops-on-unplug, Belkin support, various
- *              cleanups for problems not yet seen in the field. (db)
- * 17-oct-2001  Handle "Advance USBNET" product, like Belkin/eTEK devices,
- *              from Ioannis Mavroukakis <i.mavroukakis@btinternet.com>;
- *              rx unlinks somehow weren't async; minor cleanup.
- * 03-nov-2001  Merged GeneSys driver; original code from Jiun-Jie Huang
- *              <huangjj@genesyslogic.com.tw>, updated by Stanislav Brabec
- *              <utx@penguin.cz>.  Made framing options (NetChip/GeneSys)
- *              tie mostly to (sub)driver info.  Workaround some PL-2302
- *              chips that seem to reject SET_INTERFACE requests.
- *
- * 06-apr-2002  Added ethtool support, based on a patch from Brad Hards.
- *              Level of diagnostics is more configurable; they use device
- *              location (usb_device->devpath) instead of address (2.5).
- *              For tx_fixup, memflags can't be NOIO.
- * 07-may-2002  Generalize/cleanup keventd support, handling rx stalls (mostly
- *              for USB 2.0 TTs) and memory shortages (potential) too. (db)
- *              Use "locally assigned" IEEE802 address space. (Brad Hards)
- * 18-oct-2002  Support for Zaurus (Pavel Machek), related cleanup (db).
- * 14-dec-2002  Remove Zaurus-private crc32 code (Pavel); 2.5 oops fix,
- *              cleanups and stubbed PXA-250 support (db), fix for framing
- *              issues on Z, net1080, and gl620a (Toby Milne)
- *
- * 31-mar-2003  Use endpoint descriptors:  high speed support, simpler sa1100
- *              vs pxa25x, and CDC Ethernet.  Throttle down log floods on
- *              disconnect; other cleanups. (db)  Flush net1080 fifos

- * Zaurus is also a SA-1110 based PDA, but one using a different driver
- * (and framing) for its USB slave/gadget controller than the case above.
- *
- * For the current version of that driver, the main way that framing is
- * nonstandard (also from perspective of the CDC ethernet model!) is a
- * crc32, added to help detect when some sa1100 usb-to-memory DMA errata
- * haven't been fully worked around.  Also, all Zaurii use the same
- * default Ethernet address.
- *
- * PXA based models use the same framing, and also can't implement
- * set_interface properly.
- *
- * All known Zaurii lie about their standards conformance.  Most lie by
- * saying they support CDC Ethernet.  Some lie and say they support CDC
- * MDLM (as if for access to cell phone modems).  Someone, please beat 
- * on Sharp (and other such vendors) for a while with a cluestick.

+ * All known Zaurii lie about their standards conformance.  At least

+ * Some later models (especially PXA-25x and PXA-27x based ones) lie

+ *
+ * There are non-Zaurus products that use these same protocols too.
+ *
+ * The annoying thing is that at the same time Sharp was developing
+ * that annoying standards-breaking software, the Linux community had
+ * a simple "CDC Subset" working reliably on the same SA-1100 hardware.
+ * That is, the same functionality but not violating standards.
+ *
+ * The CDC Ethernet nonconformance points are troublesome to hosts
+ * with a true CDC Ethernet implementation:
+ *   - Framing appends a CRC, which the spec says drivers "must not" do;
+ *   - Transfers data in altsetting zero, instead of altsetting 1;
+ *   - All these peripherals use the same ethernet address.
+ *
+ * The CDC MDLM nonconformance is less immediately troublesome, since all
+ * MDLM implementations are quasi-proprietary anyway.
