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, ...). Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W.
