0001 /* orinoco_cs.c (formerly known as dldwd_cs.c)
0002  *
0003  * A driver for "Hermes" chipset based PCMCIA wireless adaptors, such
0004  * as the Lucent WavelanIEEE/Orinoco cards and their OEM (Cabletron/
0005  * EnteraSys RoamAbout 802.11, ELSA Airlancer, Melco Buffalo and others).
0006  * It should also be usable on various Prism II based cards such as the
0007  * Linksys, D-Link and Farallon Skyline. It should also work on Symbol
0008  * cards such as the 3Com AirConnect and Ericsson WLAN.
