The change to the new "persistent" network interface names was there to 
address a problem that a few people were having.  The first Ethernet 
device the kernel found would be eth0, the second eth1, third eth2.... 
This worked fine until changes to how the kernel searches for network 
devices happened.  Suddenly, people with more than one NIC could find 
that their eth0 was now eth1.  And that broke all their networking 
scripts.

So now Ethernet devices are (often) named based on where they are on 
the PCI bus.  Mine shows up as 04:00.0 in lspci, so it's enp4s0 .  You 
can add "net.ifnames=0" to the kernel command line to get rid of these 
new names.  There's no advantage in the new naming system if you only 
have 1 NIC.
