From: "John W. Linville" <linville@...driver.com>
To: jeff@...zik.org
Cc: netdev@...r.kernel.org, linux-wireless@...r.kernel.org
Subject: Please pull 'adm8211' branch of wireless-2.6
Jeff,
A new driver for 2.6.24...this one has been around for a while in
-mm and Fedora. It is reverse-engineered and still has more magic
initialization numbers than I'd like, but overall I think it would
be better to have this upstream than not.
Thanks,
John

+ This driver is for ADM8211A, ADM8211B, and ADM8211C based cards.
+ These are PCI/mini-PCI/Cardbus 802.11b chips found in cards such as:
+
+ Xterasys Cardbus XN-2411b
+ Blitz NetWave Point PC
+ TrendNet 221pc
+ Belkin F5D6001
+ SMC 2635W
+ Linksys WPC11 v1
+ Fiberline FL-WL-200X
+ 3com Office Connect (3CRSHPW796)
+ Corega WLPCIB-11
+ SMC 2602W V2 EU
+ D-Link DWL-520 Revision C
+
+ However, some of these cards have been replaced with other chips
+ like the RTL8180L (Xterasys Cardbus XN-2411b, Belkin F5D6001) or
+ the Ralink RT2400 (SMC2635W) without a model number change.
+
+ Thanks to Infineon-ADMtek for their support of this driver.
