Consistent names changed yet again?

[Tom Horsley]

I've got F21 branched installed on an alternate partition on
my system, and I noticed this nonsense. On F21 I get this:

enp5s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.134.30.143  netmask 255.255.255.0  broadcast 10.134.30.255
        inet6 fe80::20b:eff:fe0f:ed  prefixlen 64  scopeid 0x20<link>
        ether 00:0b:0e:0f:00:ed  txqueuelen 1000  (Ethernet)
        RX packets 112  bytes 13242 (12.9 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 84  bytes 10207 (9.9 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 1  collisions 0

On F20 the same hardware (note the MAC address) gives this:

p6p1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.134.30.143  netmask 255.255.255.0  broadcast 10.134.30.255
        inet6 fe80::20b:eff:fe0f:ed  prefixlen 64  scopeid 0x20<link>
        ether 00:0b:0e:0f:00:ed  txqueuelen 1000  (Ethernet)
        RX packets 1233320  bytes 144491797 (137.7 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 2058583  bytes 2951769070 (2.7 GiB)
        TX errors 0  dropped 0 overruns 0  carrier 1  collisions 0

What was the point of "consistent" interface names again?
