We are going a bit off topic here so my last post on this.
If you google you get just normal cables mostly, in my job when we needed a crossover we really asked for a crossover and not patch cable.
I think crossovers gets rarely used now, it in my opinion was a stupid invention, why make it hard when you can do it easy
Well, because years ago NIC's weren't smart enough to figure it out without a crossover cable, AND, routers and hubs were really expensive! More for home networking and small use cases than anything enterprise. I've actually seen people 'daisy chain' computers with dual NIC's and crossover cables. Ludicrous now when an 8 port gigabit switch is 10 bucks, but back then...
