It's also smart enough to handle the crossover issue itself, so it doesn't
come into this particular discussion.  (It will when it gets common enough
that ordinary machines start coming with it by default, but that'll be a
little while yet.)

There was also a variant of 100BaseT which used all four, although it's
essentially defunct.  It did need crossover cables.
