DEQNAs never worked right, even after 12 revisions.  That's why they
were dumped and the LQA was created.  For moderate loads a QNA should be
ok, though.  The big problem was that they weren't good enough for Local
Area VAXcluster use, which was a big thing in those days.  I don't think
DECnet was thrilled with them either but DECnet was more tolerant of
misbehavior.

I don't remember DEQNAs being dumped by the PDP11 operating systems.
