| 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. |

| 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. |
