/* orinoco_cs.c (formerly known as dldwd_cs.c)

*
|
|
* A driver for "Hermes" chipset based PCMCIA wireless adaptors, such
|
|
* as the Lucent WavelanIEEE/Orinoco cards and their OEM (Cabletron/
|
|
* EnteraSys RoamAbout 802.11, ELSA Airlancer, Melco Buffalo and others).
|
|
* It should also be usable on various Prism II based cards such as the
|
|
* Linksys, D-Link and Farallon Skyline. It should also work on Symbol
|
|
* cards such as the 3Com AirConnect and Ericsson WLAN.
