/* * Wavelan Pcmcia driver * * Jean II - HPLB '96 * * Reorganization and extension of the driver. * Original copyright follow. See wavelan_cs.h for details. * * This file contain the declarations of the Wavelan hardware. Note that * the Pcmcia Wavelan include a i82593 controler (see definitions in * file i82593.h). * * The main difference between the pcmcia hardware and the ISA one is * the Ethernet Controler (i82593 instead of i82586). The i82593 allow * only one send buffer. The PSA (Parameter Storage Area : EEprom for * permanent storage of various info) is memory mapped, but not the * MMI (Modem Management Interface). */ /* * Definitions for the AT&T GIS (formerly NCR) WaveLAN PCMCIA card: * An Ethernet-like radio transceiver controlled by an Intel 82593 * coprocessor. * * **************************************************************************** * Copyright 1995 * Anthony D.
