Description of problem:
PowerVS support for cloud-init requires that a ipv6 interface (with link local address) is up and running. A IPV6 interface with link local address needs ipv6_autoconf=no, but currently cloud-init does not support this configuration (the default value is yes and this causes ipv6 address fluctuations). An example of the network configuration that is expected is as listed below:
> BOOTPROTO=none
> DEVICE=env6
> HWADDR=5e:fa:03:be:50:51
> IPV6INIT=yes
> ONBOOT=yes
> STARTMODE=auto
> TYPE=Ethernet
> USERCTL=no
> IPV6_AUTOCONF=no
Version-Release number of selected component (if applicable):
cloud-init-20.3
