1 /* lasi_82596.c -- driver for the intel 82596 ethernet controller, as
8 3 primary sources of the mess --
26 03/02/2000 changes for better/correct(?) cache-flushing (deller)
33 This driver is for the Apricot 82596 bus-master interface
45 non-cached page, so we can run on 68060 in copyback mode.
52 Most of my modifications relate to the braindead big-endian
54 'big-endian' mode, it thinks a 32 bit value of 0x12345678
83 #include <linux/dma-mapping.h>
115 * the following commands are available (p5-18). The 32-bit port command
116 * must be word-swapped with the most significant word written first.
139 #define CMD_SUSP 0x4000 /* Suspend after doing cmd. */
140 #define CMD_INTR 0x2000 /* Interrupt after doing cmd. */
