*
* Changelog:
* 01-10-1997 RMK Created, READONLY version.
* 15-02-1998 RMK Added DMA support and hardware definitions.
* 15-04-1998 RMK Only do PIO if FAS216 will allow it.
* 02-05-1998 RMK Moved DMA sg list into per-interface structure.
* 27-06-1998 RMK Changed asm/delay.h to linux/delay.h
* 02-04-2000 RMK Updated for new error handling code.
