Um ifcfg doesn't handle ipv6 - just take a look at the shell script that
makes it up ...

This is highlighted by arping ... ipv6 does not use arp

I just built a minimal C7 instance to verify the behaviour...

systemctl status NetworkManager shows that it is running

ip addr add fc00::1001/124 dev eth0 adds the IP address to the interface

NetworkManager does not remove this from the interface
