download crossover cable pinout for free

This 'shortcut' doesn't work with gigabit Ethernet, and it's really not a very good way to describe a crossover cable. It's likely the confusion over this goes back to the 100BASE-TX standard, where coincidentally putting 568A wire colors on one side of a cable and 568B colors on the other side did match the 802.3 standard for 100 megabit Ethernet crossover cables. Connecting T568A colors to T568B colors does not create a 1000BASE-T crossover cable. To comply with the 1000BASE-T standard crossover function, you would not connect T568A colors to T568B colors. standards, these four wires do not pass through. For the 1000BASE-T crossover pinouts listed in the 803. If you connect a T568A colored cable to a T568B colored cable, pins 4, 5, 7, and 8 pass through.

This is easy to see because you can physically follow the pinouts. If you wire one side of an Ethernet connection with 568A colors and the other with 568B colors, it will not create a crossover cable for 1000BASE-T Ethernet connections.

A link for those standards is listed further down. When there's confusion about a topic like this, the best source is the original standards definition.
