We all know what you are talking about.

Well, I can certainly assure you that I _am_ familiar with the contents
of bus.h on _every_ NetBSD platform...
I suspect it is you who are lacking in terminology. Over and over again,
we have stated that it is NOT an "S/G list". It is a list of DMA segments,
and there is a difference in semantics between the two!
I think you should get some experience w/ other devices (i.e. not SCSI) on
other architectures (i.e. not anything like a PC).
