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.
