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

* A driver for "Hermes" chipset based PCMCIA wireless adaptors, such

* 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
