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

11 smc91c92_cs.c 1.122 2002/10/25 06:26:39
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.
