MAC Address Change

[Félim Whiteley]

hi Michael,

If you check the contents of udev rules (/etc/udev/rules.d/70-persistent-
net.rules)

You'll see some info like:
SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="00:1c:23:85:bc:50", 
ATTR{type}=="1", NAME="eth0"

It's map of your MAC address to the interface name, simply modifying the MAC 
address for the various ethernet cards will fix your issue.
