-To-do items for network drivers
--------------------------------
-
-* Move ethernet crc routine to generic code
-
-* (for 2.5) Integrate Jamal Hadi Salim's netdev Rx polling API change
-
-* Audit all net drivers to make sure magic packet / wake-on-lan /
- similar features are disabled in the driver by default.
-
-* Audit all net drivers to make sure the module always prints out a
- version string when loaded as a module, but only prints a version
- string when built into the kernel if a device is detected.
-
-* Add ETHTOOL_GDRVINFO ioctl support to all ethernet drivers.
-
-* dmfe PCI DMA is totally wrong and only works on x86

+ 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/
+
+
+Requirements
+------------
+
+1) Linux Kernel 2.6.16 or later
+ http://www.kernel.org/
+
+ You may want to configure your kernel with:
+
+ CONFIG_DEBUG_FS (optional):
+ -> Kernel hacking
+ -> Debug Filesystem
+
+2) SoftMAC IEEE 802.11 Networking Stack extension and patched ieee80211
+ modules:
+ http://softmac.sipsolutions.net/
+
+3) Firmware Files
+
+ Please try fwcutter. Fwcutter can extract the firmware from various
+ binary driver files. It supports driver files from Windows, MacOS and
+ Linux. You can get fwcutter from http://bcm43xx.berlios.de/.
+ Also, fwcutter comes with a README file for further instructions.
