Dual-Purpose Port LEDs

The dual-purpose port LEDs identify the connection as either a copper-based connector or an SFP
module. The ports can autonegotiate, or you can manually configure each dual-purpose port as either
10/100/1000 with copper connectors or as an SFP module port, but not as both types at the same time.
