(resend, please merge)
This patch adds support for the ADMtek ADM8211 card. It is not completed yet,
but I feel the code is clean enough to merge into wireless-dev. It currently
supports STA mode.

+ ---help---
+ 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.
