Modify the Rhel7/centos7 NIC to eth0

With the advent of rhel7/centos7, we found that a lot of habits and the previous use of the same habits, such as the network card, the previous naming method is eth[serial number] mode, and in the RHEL7/CENTOS7 because the interface name is automatically based on the firmware, Topology and location information to determine. Now, even if you add or remove network devices, the interface names remain fixed without re-enumeration, and the broken hardware can be replaced seamlessly. Although this change has some advantages, but for us accustomed to the former system of people, but it is a pain, now we will change the NIC to the previous eth0 this way, now RHEL7 in the following network card:
