about change the interface name

[Amaury Viera Hernández]

Hi everyone:
I'm using ubuntu server 14.04. The network card name is p1p1, but I want 
to rename it to eth0. All the official documentation in ubuntu and 
internet 
(https://help.ubuntu.com/lts/serverguide/network-configuration.html#network-config-resources) 
saids me that i need to change that in 
/etc/udev/rules.d/70-persistent-net.rules and reboot the system, but 
this isn't working for me.

Could you help me please.
I apologize for my language. Thanks in advance. Regards, Amaury.
