| 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. |
