In some linux distributions, such as RHEL7U0RC1, when we create a veth pair by "ip link add type veth", the ipv6 address for veth interfaces won't be automatically generated, so the "par_chld_ipv6" test case in containers test will fail. This is because in these distirbutions, the "/proc/sys/net/ipv6/ conf/veth*/disable_ipv6" is true for veth interfaces. Please see kernel "Documentation/networking/ip-sysctl.txt" for more detailed information.
In this patch, we will enable IPv6 address autoconfiguration for veth interfaces if disabled.
