[ih] TCP adoption in 1984

[Craig Partridge]

The first Internet router is generally believed to be the one created by
Virginia Travers and Mike Brescia (they were recognized with the IEEE
Internet award for it about 20 years ago -- I remember a lot of research
went into confirming their's was, as best one could tell, the first).

I don't recall if it supported Ethernet or simply connected two
ARPANET-technology networks (of which there were a few at the time).
