find out your MAC-address with "ifconfig -a"
make a udev-rule like below (ONE line) for the MAC
reboot the machine after that and you are done

[root at rh:~]$ cat /etc/udev/rules.d/70-persistent-net.rules
# PCI device 0x8086:0x1502 (e1000e)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="78:ac:c0:b1:76:e4", ATTR{dev_id}=="0x0",
ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
