Ethernet crossover is pretty much defunct [1]. These days (> 1998) most Ethernet hardware can sort this out automatically (called Auto MDI-X [2]). So unless you are using historical hardware, this is a non-issue. Still, for people in contact with old hardware, it is a good skill to have :-) Cheers [1] https://en.wikipedia.org/wiki/Ethernet_crossover_cable#Automatic_crossover [2] https://en.wikipedia.org/wiki/Medium_Dependent_Interface#Auto_MDI-X -- t
