Link Status
This sketch prints the ethernet link status. When the
ethernet cable is connected the link status should go to "ON".
NOTE: Only WizNet W5200 and W5500 are capable of reporting
the link status. W5100 will report "Unknown".
Hardware:
- Ethernet shield or equivalent board/shield with WizNet 5200/5500
