Yes.  The LANCE based DEQNA's from the MicroVAX II were
really strange in supporting that.  It wasn't until I
realized that the MAC address was the DEC assigned
address block prefix plus an internal prefix, plus the
DECNet node number, that I realized why I could not
talk to DECNet with my raw EtherLink I drivers, even
though the packets were formatted correctly.  8-).
