Yup.  It went through 12 revisions, but even that last "rev L" didn't work, so 
DEC eventually gave up on it and produced the LQA.  Which was a bit of a 
struggle because some aspects of the QNA API are tied to the original silicon, 
and emulating them on a very different Ethernet chip is somewhat messy.  In 
particular that applies to the address filtering.
