Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ Belkin F5U011
+ Belkin F5U111
+ CATC NetMate
+ CATC NetMate II
+ smartBridges smartNIC
+
+ This driver makes the adapter appear as a normal Ethernet interface,

+ ---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/>.
+
+ To compile this driver as a module, choose M here: the
+ module will be called usbnet.

+ * 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.

+/*
+ * 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
+ * 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)
