+    <title>The basic mac80211 driver interface</title>
+    <partintro>
+      <para>
+        You should read and understand the information contained

+        In some chapters, advanced usage is noted, that may be
+        skipped at first.

+      <para>
+        This part of the book only covers station and monitor mode

-			BCM43xx Linux Driver Project
-			============================
-
-Introduction
-------------
-
-Many of the wireless devices found in modern notebook computers are
-based on the wireless chips produced by Broadcom. These devices have
-been a problem for Linux users as there is no open-source driver
-available. In addition, Broadcom has not released specifications
-for the device, and driver availability has been limited to the
-binary-only form used in the GPL versions of AP hardware such as the
-Linksys WRT54G, and the Windows and OS X drivers.  Before this project
-began, the only way to use these devices were to use the Windows or
-OS X drivers with either the Linuxant or ndiswrapper modules. There
-is a strong penalty if this method is used as loading the binary-only
-module "taints" the kernel, and no kernel developer will help diagnose
-any kernel problems.
-
-Development
------------
-
-This driver has been developed using
-a clean-room technique that is described at
-http://bcm-specs.sipsolutions.net/ReverseEngineeringProcess. For legal
-reasons, none of the clean-room crew works on the on the Linux driver,
-and none of the Linux developers sees anything but the specifications,
-which are the ultimate product of the reverse-engineering group.
-
-Software
---------
-
-Since the release of the 2.6.17 kernel, the bcm43xx driver has been
-distributed with the kernel source, and is prebuilt in most, if not
-all, distributions.  There is, however, additional software that is
-required. The firmware used by the chip is the intellectual property
-of Broadcom and they have not given the bcm43xx team redistribution
-rights to this firmware.  Since we cannot legally redistribute
-the firmware we cannot include it with the driver. Furthermore, it
-cannot be placed in the downloadable archives of any distributing
-organization; therefore, the user is responsible for obtaining the
-firmware and placing it in the appropriate location so that the driver
-can find it when initializing.
-
-To help with this process, the bcm43xx developers provide a separate
-program named bcm43xx-fwcutter to "cut" the firmware out of a
-Windows or OS X driver and write the extracted files to the proper
-location. This program is usually provided with the distribution;
-however, it may be downloaded from
-

-The firmware is available in two versions. V3 firmware is used with
-the in-kernel bcm43xx driver that uses a software MAC layer called
-SoftMAC, and will have a microcode revision of 0x127 or smaller. The
-V4 firmware is used by an out-of-kernel driver employing a variation of
-the Devicescape MAC layer known as d80211. Once bcm43xx-d80211 reaches
-a satisfactory level of development, it will replace bcm43xx-softmac
-in the kernel as it is much more flexible and powerful.
-
-A source for the latest V3 firmware is
-
-http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o
-
-Once this file is downloaded, the command
-'bcm43xx-fwcutter -w <dir> <filename>'
-will extract the microcode and write it to directory
-<dir>. The correct directory will depend on your distribution;
-however, most use '/lib/firmware'. Once this step is completed,
-the bcm3xx driver should load when the system is booted. To see
-any messages relating to the driver, issue the command 'dmesg |
-grep bcm43xx' from a terminal window. If there are any problems,
-please send that output to Bcm43xx-dev@lists.berlios.de.
-
-Although the driver has been in-kernel since 2.6.17, the earliest
-version is quite limited in its capability. Patches that include
-all features of later versions are available for the stable kernel
-versions from 2.6.18. These will be needed if you use a BCM4318,
-or a PCI Express version (BCM4311 and BCM4312). In addition, if you
-have an early BCM4306 and more than 1 GB RAM, your kernel will need
-to be patched.	These patches, which are being updated regularly,
-are available at ftp://lwfinger.dynalias.org/patches. Look for
-combined_2.6.YY.patch. Of course you will need kernel source downloaded
-from kernel.org, or the source from your distribution.
-
-If you build your own kernel, please enable CONFIG_BCM43XX_DEBUG
-and CONFIG_IEEE80211_SOFTMAC_DEBUG. The log information provided is
-essential for solving any problems.

-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 daemon 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 cfgft1 GUI csu/dsu configurator
-				o wancfg GUI configuration file 
-				  configurator.
-				o Architectural 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 utilities 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 MultiPort PPP Support for kernels 2.2.16 and above.
-				  2.2.X kernels only
-
-				o Secured the driver UDP debugging calls
-					- All illegal network 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
-					  configuration 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 utility /usr/sbin/wpkbdmon uses keyboard leds
-					  to convey operational 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 configuration 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 network 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 functional 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-compilation.
-			
-			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.

-			o Patches for 2.4.2 kernel.
-
-			o Bug fixes to util/ make files.
-			o Bug fixes to the Setup installation script.

-beta4-2.2.1     Mar 12 2001
-
-		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.
