- 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.
