Linux-2.6.12-rc2v2.6.12-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!

+Linux WAN Router Utilities Package
+------------------------------------------------------------------------------
+Version 2.2.1

+INTRODUCTION
+
+Wide Area Networks (WANs) are used to interconnect Local Area Networks (LANs)
+and/or stand-alone hosts over vast distances with data transfer rates
+significantly higher than those achievable with commonly used dial-up
+connections.
+
+Usually an external device called `WAN router' sitting on your local network
+or connected to your machine's serial port provides physical connection to
+WAN.  Although router's job may be as simple as taking your local network
+traffic, converting it to WAN format and piping it through the WAN link, these
+devices are notoriously expensive, with prices as much as 2 - 5 times higher
+then the price of a typical PC box.
+
+Alternatively, considering robustness and multitasking capabilities of Linux,
+an internal router can be built (most routers use some sort of stripped down
+Unix-like operating system anyway). With a number of relatively inexpensive WAN
+interface cards available on the market, a perfectly usable router can be
+built for less than half a price of an external router.  Yet a Linux box
+acting as a router can still be used for other purposes, such as fire-walling,
+running FTP, WWW or DNS server, etc.
+
+This kernel module introduces the notion of a WAN Link Driver (WLD) to Linux
+operating system and provides generic hardware-independent services for such
+drivers.  Why can existing Linux network device interface not be used for
+this purpose?  Well, it can.  However, there are a few key differences between
+a typical network interface (e.g. Ethernet) and a WAN link.
+
+Many WAN protocols, such as X.25 and frame relay, allow for multiple logical
+connections (known as `virtual circuits' in X.25 terminology) over a single
+physical link.  Each such virtual circuit may (and almost always does) lead
+to a different geographical location and, therefore, different network.  As a
+result, it is the virtual circuit, not the physical link, that represents a
+route and, therefore, a network interface in Linux terms.
+
+To further complicate things, virtual circuits are usually volatile in nature
+(excluding so called `permanent' virtual circuits or PVCs).  With almost no
+time required to set up and tear down a virtual circuit, it is highly desirable
+to implement on-demand connections in order to minimize network charges.  So
+unlike a typical network driver, the WAN driver must be able to handle multiple
+network interfaces and cope as multiple virtual circuits come into existence
+and go away dynamically.
+ 
+Last, but not least, WAN configuration is much more complex than that of say
+Ethernet and may well amount to several dozens of parameters.  Some of them
+are "link-wide"  while others are virtual circuit-specific.  The same holds
+true for WAN statistics which is by far more extensive and extremely useful
+when troubleshooting WAN connections.  Extending the ifconfig utility to suit
+these needs may be possible, but does not seem quite reasonable.  Therefore, a
+WAN configuration utility and corresponding application programmer's interface
+is needed for this purpose.
+
+Most of these problems are taken care of by this module.  Its goal is to
+provide a user with more-or-less standard look and feel for all WAN devices and
+assist a WAN device driver writer by providing common services, such as:
+
+ o User-level interface via /proc file system
+ o Centralized configuration
+ o Device management (setup, shutdown, etc.)
+ o Network interface management (dynamic creation/destruction)
+ o Protocol encapsulation/decapsulation
+
+To ba able to use the Linux WAN Router you will also need a WAN Tools package
+available from
+
+	ftp.sangoma.com/pub/linux/current_wanpipe/wanpipe-X.Y.Z.tgz
+
+where vX.Y.Z represent the wanpipe version number.

+ACKNOWLEDGEMENTS
+
+This product is based on the WANPIPE(tm) Multiprotocol WAN Router developed
+by Sangoma Technologies Inc. for Linux 2.0.x and 2.2.x.  Success of the WANPIPE
+together with the next major release of Linux kernel in summer 1996 commanded
+adequate changes to the WANPIPE code to take full advantage of new Linux
+features.
+
+Instead of continuing developing proprietary interface tied to Sangoma WAN
+cards, we decided to separate all hardware-independent code into a separate
+module and defined two levels of interfaces - one for user-level applications
+and another for kernel-level WAN drivers.  WANPIPE is now implemented as a
+WAN driver compliant with the WAN Link Driver interface.  Also a general
+purpose WAN configuration utility and a set of shell scripts was developed to 
+support WAN router at the user level.
+
+Many useful ideas concerning hardware-independent interface implementation
+were given by Mike McLagan <mike.mclagan@linux.org> and his implementation
+of the Frame Relay router and drivers for Sangoma cards (dlci/sdla).
+
+With the new implementation of the APIs being incorporated into the WANPIPE,
+a special thank goes to Alan Cox in providing insight into BSD sockets.
+
+Special thanks to all the WANPIPE users who performed field-testing, reported
+bugs and made valuable comments and suggestions that help us to improve this
+product.
+
+
+
+NEW IN THIS RELEASE
+
+	o Updated the WANCFG utility
+		Calls the pppconfig to configure the PPPD
+		for async connections.
+
+	o Added the PPPCONFIG utility
+		Used to configure the PPPD dameon for the
+		WANPIPE Async PPP and standard serial port.
+		The wancfg calls the pppconfig to configure
+		the pppd.
+
+	o Fixed the PCI autodetect feature.  
+		The SLOT 0 was used as an autodetect option
+		however, some high end PC's slot numbers start
+		from 0. 
+
+	o This release has been tested with the new backupd
+	  daemon release.

+				o New CHDLC and Frame Relay drivers
+				o PPP and X25 are not supported in this release    
+
+2.1.1	Nov 30, 1999		o PPP support for S514 PCI Cards

+				  configurator.
+				o Architectual directory changes.
+
+beta-2.1.4 Jul 2000		o Dynamic interface configuration:
+					Network interfaces reflect the state
+					of protocol layer.  If the protocol becomes
+					disconnected, driver will bring down
+					the interface.  Once the protocol reconnects
+					the interface will be brought up. 
+					
+					Note: This option is turned off by default.
+
+				o Dynamic wanrouter setup using 'wanconfig':
+					wanconfig utility can be used to
+					shutdown,restart,start or reconfigure 
+					a virtual circuit dynamically.
+				     
+					Frame Relay:  Each DLCI can be: 
+						      created,stopped,restarted and reconfigured
+						      dynamically using wanconfig.
+					
+						      ex: wanconfig card wanpipe1 dev wp1_fr16 up
+				  
+				o Wanrouter startup via command line arguments:
+					wanconfig also supports wanrouter startup via command line
+					arguments.  Thus, there is no need to create a wanpipe#.conf
+					configuration file.  
+
+				o Socket based x25api update/bug fixes.
+					Added support for LCN numbers greater than 255.
+					Option to pass up modem messages.
+					Provided a PCI IRQ check, so a single S514
+					card is guaranteed to have a non-sharing interrupt.
+
+				o Fixes to the wancfg utility.
+				o New FT1 debugging support via *pipemon utilities.
+				o Frame Relay ARP support Enabled.
+
+beta3-2.1.4 Jul 2000		o X25 M_BIT Problem fix.
+				o Added the Multi-Port PPP
+				  Updated utilites for the Multi-Port PPP.
+
+2.1.4	Aut 2000
+				o In X25API:
+					Maximum packet an application can send
+					to the driver has been extended to 4096 bytes.
+
+					Fixed the x25 startup bug. Enable 
+					communications only after all interfaces
+					come up.  HIGH SVC/PVC is used to calculate
+					the number of channels.
+					Enable protocol only after all interfaces
+					are enabled.
+
+				o Added an extra state to the FT1 config, kernel module.
+				o Updated the pipemon debuggers.
+
+				o Blocked the Multi-Port PPP from running on kernels
+				  2.2.16 or greater, due to syncppp kernel module
+				  change. 
+	  
+beta1-2.1.5 	Nov 15 2000
+				o Fixed the MulitPort PPP Support for kernels 2.2.16 and above.
+				  2.2.X kernels only
+
+				o Secured the driver UDP debugging calls
+					- All illegal netowrk debugging calls are reported to
+					  the log.
+					- Defined a set of allowed commands, all other denied.
+					
+				o Cpipemon
+					- Added set FT1 commands to the cpipemon. Thus CSU/DSU
+					  configuraiton can be performed using cpipemon.
+					  All systems that cannot run cfgft1 GUI utility should
+					  use cpipemon to configure the on board CSU/DSU.
+
+
+				o Keyboard Led Monitor/Debugger
+					- A new utilty /usr/sbin/wpkbdmon uses keyboard leds
+					  to convey operatinal statistic information of the 
+					  Sangoma WANPIPE cards.
+					NUM_LOCK    = Line State  (On=connected,    Off=disconnected)
+					CAPS_LOCK   = Tx data     (On=transmitting, Off=no tx data)
+					SCROLL_LOCK = Rx data     (On=receiving,    Off=no rx data
+					
+				o Hardware probe on module load and dynamic device allocation
+					- During WANPIPE module load, all Sangoma cards are probed
+					  and found information is printed in the /var/log/messages.
+					- If no cards are found, the module load fails.
+					- Appropriate number of devices are dynamically loaded 
+					  based on the number of Sangoma cards found.
+
+					  Note: The kernel configuraiton option 
+						CONFIG_WANPIPE_CARDS has been taken out.
+					
+				o Fixed the Frame Relay and Chdlc network interfaces so they are
+				  compatible with libpcap libraries.  Meaning, tcpdump, snort,
+				  ethereal, and all other packet sniffers and debuggers work on
+				  all WANPIPE netowrk interfaces.
+					- Set the network interface encoding type to ARPHRD_PPP.
+					  This tell the sniffers that data obtained from the
+					  network interface is in pure IP format.
+				  Fix for 2.2.X kernels only.
+				
+				o True interface encoding option for Frame Relay and CHDLC
+					- The above fix sets the network interface encoding
+					  type to ARPHRD_PPP, however some customers use
+					  the encoding interface type to determine the
+					  protocol running.  Therefore, the TURE ENCODING
+					  option will set the interface type back to the
+					  original value.  
+
+					  NOTE: If this option is used with Frame Relay and CHDLC
+						libpcap library support will be broken.  
+						i.e. tcpdump will not work.
+					Fix for 2.2.x Kernels only.
+						
+				o Ethernet Bridgind over Frame Relay
+					- The Frame Relay bridging has been developed by 
+					  Kristian Hoffmann and Mark Wells.  
+					- The Linux kernel bridge is used to send ethernet 
+					  data over the frame relay links.
+					For 2.2.X Kernels only.
+
+				o Added extensive 2.0.X support. Most new features of
+				  2.1.5 for protocols Frame Relay, PPP and CHDLC are
+				  supported under 2.0.X kernels. 
+
+beta1-2.2.0 	Dec 30 2000
+				o Updated drivers for 2.4.X kernels.
+				o Updated drivers for SMP support.
+				o X25API is now able to share PCI interrupts.
+				o Took out a general polling routine that was used
+				  only by X25API. 
+				o Added appropriate locks to the dynamic reconfiguration
+				  code.
+				o Fixed a bug in the keyboard debug monitor.
+
+beta2-2.2.0	Jan 8 2001
+				o Patches for 2.4.0 kernel
+				o Patches for 2.2.18 kernel
+				o Minor updates to PPP and CHLDC drivers.
+				  Note: No functinal difference. 
+
+beta3-2.2.9	Jan 10 2001
+				o I missed the 2.2.18 kernel patches in beta2-2.2.0
+				  release.  They are included in this release.
+
+Stable Release
+2.2.0		Feb 01 2001
+				o Bug fix in wancfg GUI configurator.
+					The edit function didn't work properly.
+
+
+bata1-2.2.1	Feb 09 2001
+			o WANPIPE TTY Driver emulation. 
+			  Two modes of operation Sync and Async.
+				Sync: Using the PPPD daemon, kernel SyncPPP layer
+				      and the Wanpipe sync TTY driver: a PPP protocol 
+				      connection can be established via Sangoma adapter, over
+				      a T1 leased line.
+			
+				      The 2.4.0 kernel PPP layer supports MULTILINK
+				      protocol, that can be used to bundle any number of Sangoma
+				      adapters (T1 lines) into one, under a single IP address.
+				      Thus, efficiently obtaining multiple T1 throughput. 
+
+				      NOTE: The remote side must also implement MULTILINK PPP
+					    protocol.
+
+				Async:Using the PPPD daemon, kernel AsyncPPP layer
+				      and the WANPIPE async TTY driver: a PPP protocol
+				      connection can be established via Sangoma adapter and
+				      a modem, over a telephone line.
+
+				      Thus, the WANPIPE async TTY driver simulates a serial
+				      TTY driver that would normally be used to interface the 
+				      MODEM to the linux kernel.
+				
+			o WANPIPE PPP Backup Utility
+				This utility will monitor the state of the PPP T1 line.
+				In case of failure, a dial up connection will be established
+				via pppd daemon, ether via a serial tty driver (serial port), 
+				or a WANPIPE async TTY driver (in case serial port is unavailable).
+				
+				Furthermore, while in dial up mode, the primary PPP T1 link
+				will be monitored for signs of life.  
+
+				If the PPP T1 link comes back to life, the dial up connection
+				will be shutdown and T1 line re-established.
+			
+
+			o New Setup installation script.
+				Option to UPGRADE device drivers if the kernel source has
+				already been patched with WANPIPE.
+
+				Option to COMPILE WANPIPE modules against the currently 
+				running kernel, thus no need for manual kernel and module
+				re-compilatin.
+			
+			o Updates and Bug Fixes to wancfg utility.
+
+bata2-2.2.1	Feb 20 2001
+
+			o Bug fixes to the CHDLC device drivers.
+				The driver had compilation problems under kernels
+				2.2.14 or lower.
+
+			o Bug fixes to the Setup installation script.
+				The device drivers compilation options didn't work
+				properly.
+
+			o Update to the wpbackupd daemon.  
+				Optimized the cross-over times, between the primary
+				link and the backup dialup.
+
+beta3-2.2.1	Mar 02 2001
+			o Patches for 2.4.2 kernel.
+
+			o Bug fixes to util/ make files.
+			o Bug fixes to the Setup installation script.
+
+			o Took out the backupd support and made it into

+
+		o Fix to the Frame Relay Device driver.
+			IPSAC sends a packet of zero length
+			header to the frame relay driver.  The
+			driver tries to push its own 2 byte header
+			into the packet, which causes the driver to
+			crash.
+
+		o Fix the WANPIPE re-configuration code.
+			Bug was found by trying to run  the cfgft1 while the
+			interface was already running.  
+
+		o Updates to cfgft1.
+			Writes a wanpipe#.cfgft1 configuration file
+			once the CSU/DSU is configured. This file can
+			holds the current CSU/DSU configuration.
