/*
* This is a generic "USB networking" framework that works with several
- * kinds of full and high speed networking devices:
+ * kinds of full and high speed networking devices: host-to-host cables,
+ * smart usb peripherals, and actual Ethernet adapters.
*
- * + 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
- * after several sequential framing errors. (Johannes Erdfelt)
- * 22-aug-2003 AX8817X support (Dave Hollis).
- * 14-jun-2004 Trivial patch for AX8817X based Buffalo LUA-U2-KTX in Japan
- * (Neil Bortnak)
- * 03-nov-2004 Trivial patch for KC2190 (KC-190) chip. (Jonathan McDowell)
- *
- * 01-feb-2005 AX88772 support (Phil Chang & Dave Hollis)
- *-------------------------------------------------------------------------*/
+ * These devices usually differ in terms of control protocols (if they
+ * even have one!) and sometimes they define new framing to wrap or batch
+ * Ethernet packets. Otherwise, they talk to USB pretty much the same,
+ * so interface (un)binding, endpoint I/O queues, fault handling, and other
+ * issues can usefully be addressed by this framework.
