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.
