    You can use ifconfig command parameter to set the connection media type.
The supporting connection type and the ifconfig command parameters are listed
below (suppose the NIC is hooked on interface 4):

    1) Auto-negotiation    : ifconfig en4 media autoselect
    2) 100Mbps Half-duplex : ifconfig en4 media 100baseTX mediaopt half-duplex
    3) 100Mbps Full-duplex : ifconfig en4 media 100baseTX mediaopt full-duplex
    4) 10Mbps  Half-duplex : ifconfig en4 media 10baseT/UTP mediaopt half-duplex
    5) 10Mbps  Full-duplex : ifconfig en4 media 10baseT/UTP mediaopt full-duplex
