The de(4) driver had some #ifdef'd code in it to use NetBSD's version of bus_dma. I mostly rewrote that and restructured the driver to store metadata about descriptors differently. There's still an #ifdef for bus_dma so it can run both with and without bus_dma for now. It's been running happily on my ds20 for a couple of days both ways now, so I'd appreciate it if other folks could test the patches. By default, the patches leave bus_dma disabled, and I'd prefer that people test the driver both with and without bus_dma. To enable bus_dma, simply edit the line in if_de.c that has '//#define TULIP_BUS_DMA' and removing the leading '//' from the line. Thanks.
