3 | A PCMCIA ethernet driver for SMC91c92-based cards. | |
4 | ||
5 | This driver supports Megahertz PCMCIA ethernet cards; and | |
6 | Megahertz, Motorola, Ositech, and Psion Dacom ethernet/modem | |
7 | multifunction cards. | |

12 | ||
13 | This driver contains code written by Donald Becker | |
14 | (becker@scyld.com), Rowan Hughes (x-csrdh@jcu.edu.au), | |
15 | David Hinds (dahinds@users.sourceforge.net), and Erik Stahlman | |
16 | (erik@vt.edu). Donald wrote the SMC 91c92 code using parts of | |
17 | Erik's SMC 91c94 driver. Rowan wrote a similar driver, and I've | |
18 | incorporated some parts of his driver here. I (Dave) wrote most | |
19 | of the PCMCIA glue code, and the Ositech support code. Kelly | |
20 | Stephens (kstephen@holli.com) added support for the Motorola | |
21 | Mariner, with help from Allen Brost. | |
