- /*======================================================================
- 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.

- CCAE support. Drivers merged back together, and shared-memory
- Socket EA support added, by Ken Raeburn, September 1995.
