vpp_device: disable IPv6 in containers
Even with IPv6 nd disabled in VMs, there are IPv6 packets coming from DuT: --dut_if2_mac ba:dc:0f:fe:02:05 ... dst = 33:33:00:00:00:01 src = ba:dc:0f:fe:02:05 Docker disables IPv6 by default on interfaces it manages, which doesn't include VF interfaces. Disabling IPv6 in containers using sysctl may fix this. Change-Id: Idba506653442a3da2cd82e69cedddb3294d92788 Signed-off-by: Juraj Linkeš <juraj.linkes@pantheon.tech>
