[CentOS] pls help about changing network card but assign to another ethx

Hi 

I change eth1 from realtek to dlink but the centos is showing eth2 instead of eth1

In another version of linux, I can change 70-persistent-net.rules but

I check /etc/udev/rules.d/70-persistent-net.rules but it doesn't  have the file 70-persistent-net.rules

please help 

Thank you
