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.
