/* orinoco_cs.c 0.13b	- (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
