/*====================================================================== 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: Written 1993-94 by Donald Becker.
