fc62ec015b
This patch is rather big because I had to significantly redesign the driver to make the busdma conversion possible. Most notably, hardware and software structures were carefully splitted to get rid of all the structs overlapping evilness. Special thanks to phk and Richard Puga <puga@mauibuilt.com> for providing me with fxp(4) hardware to do this work. Thanks to marcel for testing this on ia64, and to Fred Clift <fclift@verio.net> for testing this on alpha. Tested on: i386, ia64, alpha
