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

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