workstation (call it WStation,
I know the above is oversimplified, but I hope it's reasonably correct.
(I'm pretty sure I should have talked about sending packets to MAC
addresses at times, but I don't know or remember enough to do that, and
I think (??) this oversimplified view is adequate for my purposes.)
