Yes... I had wires written originally and decided to switch to pairs
and forgot to change a number. Clearly it was a typo. I don't
believe it makes my point about gigabit ethernet requiring
significantly more complexity to operate in ("just") a half-duplex
mode compared to the 10/100 cases any less valid. If you'd like to
address instead, you know, the point I was making: ie gigabit ethernet
is so different from 10/100 you shouldn't group them together, then I
am all ears.
