Disable IPv6 automatic SLAAC by linux kernel and handle it manually. This allows us gaining control on local address acquisition and set addresses and routing properly. It will also allow us to run in ping mode without a tun iface. Related: OS#4434 Change-Id: Iae59cf6ffb181357e10b3080a5c751bd454f4a1f
