4 A fmvj18x (and its compatibles) PCMCIA client driver
6 Contributed by Shingo Fujimoto, shingo@flab.fujitsu.co.jp
8 TDK LAK-CD021 and CONTEC C-NET(PC)C support added by
9 Nobuhiro Katayama, kata-n@po.iijnet.or.jp
11 The PCMCIA client code is based on code written by David Hinds.
12 Network code is based on the "FMV-18x driver" by Yutaka TAMIYA
13 but is actually largely Donald Becker's AT1700 driver, which
14 carries the following attribution:
