Coupler Crossover:
To make a crossover cable, we want to swap pins 1 and 3, and pins 2 and 6. When
you hold an RJ45 connector by the cable so the metal connectors face toward you,
pin 1 is on the left side. If you match the inner assembly to the RJ45 connector,
you'll see which is pin 1. Swap pins 1 and 3, and then swap pins 2 and 6.
