Title: Medium: IPaddr2: fix waiting the completion of IPv6 address allocation

Make sure the IPv6 address allocation has completed by checking
a tentative flag in the ip command output rather than using ping.
Using ping may cause IPv6 duplicate address detection fail in
LVS configuration. The behavior may vary depending on the kernel version.

See below for details:
