Yetch, this was many years ago, I think I wrote this driver when I lived 
in Boston, so I do not remember the specifics.
I had the same docs that are on bitsavers though.

Anyway, the DEQNA is a quite buggy animal, and it may be that I did not 
get ALLMULTI to work as the docs said. The DELQA works much better, but 
I did not have one of those at hand then.

I probably did not try too much with it, more than 12 addresses could as 
well turn on promiscuous mode.
