The document answers:

"Many later Macintosh computers are able to use either a straight-through
Ethernet cable or a crossover Ethernet cable automatically through the use
of Auto-Medium Dependent Interface Crossover (Auto-MDIX). Other Macintosh
computers require the use of an Ethernet crossover cable because they only
work with the Medium Dependent Interface (MDI)

Auto-MDIX automatically switches between MDI and MDI-X, which allows either
type of cable to be connected regardless of whether you are connecting two
computers directly, or you are connecting to a hub or switch. MDI devices
connected to Auto-MDIX devices do not require a crossover Ethernet cable."
