add this two lines

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:xx", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:xx", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

instead xx:xx should be hardware address.

#cd /etc/sysconfig/network-scripts/
#cp ifcfg-eno1 ifcfg-eth0
#cp ifcfg-eno2 ifcfg-eth1

use ifcfg-eth0 conf file to change param.
