-
- A fmvj18x (and its compatibles) PCMCIA client driver
-
- Contributed by Shingo Fujimoto, shingo@flab.fujitsu.co.jp
-
- TDK LAK-CD021 and CONTEC C-NET(PC)C support added by
- Nobuhiro Katayama, kata-n@po.iijnet.or.jp
-
- 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:
