    A PCMCIA ethernet driver for NS8390-based cards

    This driver supports the D-Link DE-650 and Linksys EthernetCard
    cards, the newer D-Link and Linksys combo cards, Accton EN2212
    cards, the RPTI EP400, and the PreMax PE-200 in non-shared-memory
    mode, and the IBM Credit Card Adapter, the NE4100, the Thomas
    Conrad ethernet card, and the Kingston KNE-PCM/x in shared-memory
    mode.  It will also handle the Socket EA card in either mode.

    pcnet_cs.c 1.153 2003/11/09 18:53:09

    The network driver code is based on Donald Becker's NE2000 code:

    Written 1992,1993 by Donald Becker.
    Copyright 1993 United States Government as represented by the
    Director, National Security Agency.
    Donald Becker may be reached at becker@scyld.com

    Based also on Keith Moore's changes to Don Becker's code, for IBM
    CCAE support.  Drivers merged back together, and shared-memory
    Socket EA support added, by Ken Raeburn, September 1995.
