The driver must be rewritten to use bus_dma(9). It will not be re-enabled as-is, since many architectures will never have vtophys. In particular, amd64.
"testing" won't help. Nor is there any other information needed. The problem is obvious. To a kernel developer, the commit message speaks far enough to the issue. If you don't have the skill to do it, well that's too bad... there also appears to be a lack of people who want to rewrite the driver. It is a very old and rare chip. There are far more important issues than supporting such ancient devices. So you are better off getting some other device. >I got access to a D-Link DFE-580TX PCI network device (Sundance Technologies >ST201 10/100 Ethernet device) recently and decided to do some preliminary >experiments on amd64 involving the corresponding driver on OpenBSD.
