+ *	WaveLAN ISA driver

+ *		Jean II - HPLB '96
+ *
+ * Reorganisation and extension of the driver.
+ * Original copyright follows. See wavelan.p.h for details.
+ *
+ * This file contains the declarations for the WaveLAN hardware. Note that
+ * the WaveLAN ISA includes a i82586 controller (see definitions in
+ * file i82586.h).
+ *
+ * The main difference between the ISA hardware and the PCMCIA one is
+ * the Ethernet controller (i82586 instead of i82593).
+ * The i82586 allows multiple transmit buffers.  The PSA needs to be accessed
+ * through the host interface.
