2 /* lasi_82596.c -- driver for the intel 82596 ethernet controller, as
9 3 primary sources of the mess --
27 03/02/2000 changes for better/correct(?) cache-flushing (deller)
34 This driver is for the Apricot 82596 bus-master interface
46 non-cached page, so we can run on 68060 in copyback mode.
53 Most of my modifications relate to the braindead big-endian
55 'big-endian' mode, it thinks a 32 bit value of 0x12345678
82 #include <linux/dma-mapping.h>
114 * the following commands are available (p5-18). The 32-bit port command
115 * must be word-swapped with the most significant word written first.
