Well, it's not entirely inconsistent: PPP does the same thing. I _think_
PPP has always done this.
I can't remember if I thought about this at the time, but I think that my
logic at the time might have been (would have been?) that the connections
over a given PPP device may not, in general, have anything to do with one
another. Therefore, it is probably more useful to know the statistics
for _this_ connection, unconfused by the stats for previous connections.
