    fmvj18x_cs.c 2.8 2002/03/23

    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:
