20fe2176e5 [PATCH] zd1211rw: AL2230 ZD1211B vendor sync
This patch synchronizes our code to some recent vendor driver modifications.
A new PHY layout is supported, some values are tweaked, and the AL2230 is now
programmed over a new interface which is many times faster.

The vendor driver resets the IFS value every time the channel changes,
to this one.

The vendor driver chooses this value based on an ifndef ASIC,
and ASIC is never defined.

fde627b54c [PATCH] zd1211rw: Packet filter fix for managed (STA) mode
I had problems with my AVM Fritz!Box access point. It appeared
that the AP deauthorized me and the softmac didn't reconnect me.
This patch handles the problem.

b269825b9b [PATCH] zd1211rw: Fixed endianess issue with length info tag detection
Discovered a problem while accessing www.python.org on my PPC32.
The problem was pretty consistent for all sticks. The reason was
that while testing for the length info tag, I ignored the
endianess of the host system.

Please recognize that converting the constant to little endian, we
create faster code.

40da08bca6 [PATCH] zd1211rw: Fix software encryption/decryption
Apparently the ZD1211 doesn't mind, but the ZD1211B absolutely must be
told that encryption is happening in software.

99f65f25c1 [PATCH] zd1211rw: Fixes radiotap header
There has been a problem in the radiotap header. Monitor mode
works now with tcpdump 3.94 + libpcap 0.9.4. ethereal 0.99.0 +
libpcap 0.9.4 is broken, because it doesn't find the right offset
for the IEEE 802.11 header.

We will reimplement halt-clearing later, when we have periodic
housekeeping routines in place. This will do as a temporary fix, the
EPIPE case has not yet been seen.

e85d0918b5 [PATCH] ZyDAS ZD1211 USB-WLAN driver
There are 60+ USB wifi adapters available on the market based on the ZyDAS
ZD1211 chip.

Unlike the predecessor (ZD1201), ZD1211 does not have a hardware MAC, so most
data operations are coordinated by the device driver. The ZD1211 chip sits
alongside an RF transceiver which is also controlled by the driver. Our driver
currently supports 2 RF types, we know of one other available in a few marketed
products which we will be supporting soon.

Our driver also supports the newer revision of ZD1211, called ZD1211B. The
initialization and RF operations are slightly different for the new revision,
but the main difference is 802.11e support. Our driver does not support the
QoS features yet, but we think we know how to use them.

This driver is based on ZyDAS's own GPL driver available from www.zydas.com.tw.
ZyDAS engineers have been responsive and supportive of our efforts, so thumbs
up to them. Additionally, the firmware is redistributable and they have
provided device specs.

This driver has been written primarily by Ulrich Kunitz and myself. Graham
Gower, Greg KH, Remco and Bryan Rittmeyer have also contributed. The
developers of ieee80211 and softmac have made our lives so much easier- thanks!

We maintain a small info-page: http://zd1211.ath.cx/wiki/DriverRewrite

If there is enough time for review, we would like to aim for inclusion in
2.6.18. The driver works nicely as a STA, and can connect to both open and
encrypted networks (we are using software-based encryption for now). We will
work towards supporting more advanced features in the future (ad-hoc, master
mode, 802.11a, ...).
