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

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