transport IPV6
scenario:
---------
Brought up sc-1 and sc-2 with link-local ipv6 address.
Both the controllers formed a cluster and sc-1 came up as active and sc-2 as
standby.
Now on sc-1 assigned global ip address 2001:db8:85a3::8a2e:370:7334
Now restarted opensaf on sc-1 as /etc/init.d/opensafd restart.
Failover takes place. sc-2 becomes active. sc-1 comes as active with new global
ip as expected.
Dtmd on sc-2 hoggs the system. cpu usage goes up to 95%.
It generated ~5GB of log file.
