+ A fmvj18x (and its compatibles) PCMCIA client driver

+
+ 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
