fmvj18x_cs.c 2.8 2002/03/23 |
|
|
|
A fmvj18x (and its compatibles) PCMCIA client driver |
|
|
|
Contributed by Shingo Fujimoto, [email protected] |
|
|
|
TDK LAK-CD021 and CONTEC C-NET(PC)C support added by |
|
Nobuhiro Katayama, [email protected] |
|
|
|
The PCMCIA client code is based on code written by David Hinds. |
|
Network code is based on the "FMV-18x driver" by Yutaka TAMIYA |
|
but is actually largely Donald Becker's AT1700 driver, which |
|
carries the following attribution: |
