5.5.6 MDIX
W5500 does not support auto-MDIX feature.
Thus, user should use straight-through cables to connect to other switches or routers and
crossover cables to connect to devices such as servers, workstations or another W5500.
However, user can use either type of cable to connect to other devices with auto-MDIX
enabled, and the interface automatically corrects for any incorrect cabling.
