   4    A PCMCIA ethernet driver for NS8390-based cards
   5
   6    This driver supports the D-Link DE-650 and Linksys EthernetCard
   7    cards, the newer D-Link and Linksys combo cards, Accton EN2212
   8    cards, the RPTI EP400, and the PreMax PE-200 in non-shared-memory
   9    mode, and the IBM Credit Card Adapter, the NE4100, the Thomas
  10    Conrad ethernet card, and the Kingston KNE-PCM/x in shared-memory
  11    mode.  It will also handle the Socket EA card in either mode.

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

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