NetBSD version of if_de :-).....

Possibly not. It's getting time for them to do so. I've had it on my list for
a while to do if_wx as a sample for Bill Paul and others to think about.

Others have made assertions that we should 'just use bounce buffers instead of
fixing drivers'. That doesn't work because you still have a shared resource to
tell unaware drivers.

This has to get fixed sooner or later anyway. For crying out loud, even Linux
has figured this out.
