burst size when transferring data. - Changed ledma attach code to pay attention to the PROM's notion of what cable type is being used. Note that this patch does not fix the problem recently discussed on port-sparc; in most cases the PROM doesn't know what cable type is being used. The default is now TP rather than AUI, though. A complete fix is forthcoming.
