/*
* 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 controller (see definitions in
* file i82593.h).
*
* The main difference between the pcmcia hardware and the ISA one is
* the Ethernet Controller (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).
