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. | |
