 Each Ethernet hardware connection has its own defined unique MAC number, no need to define another. If Ethernet bonding were being used there maybe a need to use this stanza. Each Ethernet hardware connection has its own defined unique MAC number, no need to define another.

 +The "modern" way to specify static ip address as address 192.168.1.0/24'' this automatically assigns the network, netmask and broadcast addresses.
 +
 +The old fashion way was to manual assign as follows:
 +address 192.168.1.32
 +network 192.168.1.0
 +netmask 255.255.255.0
 +broadcast 192.168.1.255
 +Perhaps this is still required in special cases?
