  1 /* orinoco_cs.c (formerly known as dldwd_cs.c)
  2  *
  3  * A driver for "Hermes" chipset based PCMCIA wireless adaptors, such
  4  * as the Lucent WavelanIEEE/Orinoco cards and their OEM (Cabletron/
  5  * EnteraSys RoamAbout 802.11, ELSA Airlancer, Melco Buffalo and others).
  6  * It should also be usable on various Prism II based cards such as the
  7  * Linksys, D-Link and Farallon Skyline. It should also work on Symbol
  8  * cards such as the 3Com AirConnect and Ericsson WLAN.
