Ticket: CM-8610
Reviewed By: Roopa, Nikhil G
Testing Done:
It used to be a silent exception, but not anymore because we catch it and log
accordingly (error) and flag the ifaceobj so that ifupdown2 returns 1.
$ cat /etc/network/interfaces
auto tap0
iface tap0
mtu 9000
address 172.17.28.0/31
$ ifreload -a
$ echo "address 2002:17:27:17/120" >> /etc/network/interfaces
$ ifreload -a
$ echo $?
0
$ # applying this patch
$ ifreload -a
