-****  HOWTO get bcm43xx-dscape running  ****
-****                                    ****
-
-This is a port of the bcm43xx driver for the devicescape ieee802.11
-stack. The devicescape ieee802.11 stack is an advanced out-of-mainline
-802.11 protocol module.
-I will call the "devicescape ieee802.11 stack" simply "dscape" in the
-following text.
-
-
-*** Setting up the bcm43xx driver with dscape is currently non-trivial,
-*** as several modifications to the kernel and the userland
-*** wpa_supplicant tool are required. We are working on it...
-
-
-1)  You need to patch the kernel with the ieee80211-devicescape stack
-    and the bcm43xx-dscape port.
-    Both are available in one cummulative at:
-    ftp://ftp.bu3sch.de/bcm43xx-snapshots/all-in-one/bcm43xx-dscape/
-    Read the instructions on http://bcm43xx.berlios.de/ for how to apply
-    this patch.
-
-    Patch the kernel, compile and install it.
-    When configuring, enable
-    "Networking/Generic IEEE 802.11 Networking Stack (dscape)"
-    and
-    "Device Drivers/Network device support/Wireless LAN (non-hamradio)/Broadcom BCM43xx wireless support (DeviceScape stack)"
-    Reboot.
-
-2)  Set up a wpa_supplicant config file in /etc/wpa_supplicant.conf
-    Here is an example for an AES WPA encrypted network:
-
-	# WPA AES encryption
-	ctrl_interface=/var/run/wpa_supplicant
-	network={
-		ssid="ACCESSPOINT_SSID"
-		key_mgmt=WPA-PSK
-		proto=WPA
-		pairwise=CCMP TKIP
-		group=CCMP TKIP
-		psk="MY PASSPHRASE"
-		priority=3
-	}
-
-3)  Take a bottle of your favourite beer, open it and take a swallow.
-
-4)  Now it's time to bring the driver up.
-    Do modprobe bcm43xx-d80211 to load the driver.
-    There is an ugly bash script to bring the driver up after insmod.
-    It is found in the "scripts" subdirectory of the patched kernel
-    tree and is called "bcm43xx-d80211-sta_up.sh".
-    Call scripts/bcm43xx-d80211-sta_up.sh --help to get some usage information.
-    It may suffice to call scripts/bcm43xx-d80211-sta_up.sh without any parameters. See
-    the help. Default parameters, which are used when called without parameters,
-    are explained there.
-
-5)  If you want to access the internet, make sure your default route
-    is correctly set up with your gateway's IP:
-    route add default gw 192.168.xxx.xxx
-
-6)  Take another swallow from your bottle of beer and test if it works:
-    ping www.kernel.org
-
-7)  If it works, drink the rest of your beer. Otherwise read this HOWTO again,
-    and again and again. Complain to bcm43xx-dev@lists.berlios.de, if it still
-    does not work.

-			BCM43xx Linux Driver Project
-			============================
-
-About this software
--------------------
-
-The goal of this project is to develop a linux driver for Broadcom
-BCM43xx chips, based on the specification at 
-http://bcm-specs.sipsolutions.net/
-
-The project page is http://bcm43xx.berlios.de/
-
-This is a port of the bcm43xx driver for the devicescape ieee802.11
-stack.  
-
-Requirements
-------------
-
-1)	Linux Kernel 2.6.16 or later
-	http://www.kernel.org/
-
-	See Documentation/networking/bcm43xx-d80211-HOWTO.txt for further 
-	instructions. 
-
-2)	Firmware Files
-
-	Please try bcm43xx-fwcutter. It can extract the firmware from various 
-	binary driver files and supports driver files from Windows, MacOS and 
-	Linux. You can get bcm43xx-fwcutter from http://bcm43xx.berlios.de/.
-	Also, bcm43xx-fwcutter comes with a README file for further instructions.
