Use global IPv6 addresses for DTM_NODE_IP in /etc/opensaf/dtmd.conf ,but discovered that OpenSAF was sending broadcast messages from port 6900 using the link local address of the interface instead of the global address listed in dtmd.conf. Port 6900 is for DTM_UDP_BCAST_REV_PORT.

OpenSAF Dtm Broadcast Sender and Listener should segregate IPV6 link local / global address
and link local should be disable and force broadcast communications through the global address when global address is configured in dtmd.conf and vice-versa.

Following are the test case to reproduce :

Test case 1) Bring-up 2 -Controllers with TCP IPV6 Scope:Global , when A Third party IPV6 UDP Application bind to same Opensf dtm port 6900 on Scope:Link Local Mcast address to receive broadcast messages.

 - Third party IPv6 UDP Application is receiveing  broadcast messages

Test case 2) Bring-up 2 -Controllers with TCP IPv6 Scope:Link Local , when A Third party IPv6 UDP Application bind to same Opensf dtm port 6900 on Scope:Global Mcast address to receive broadcast messages.

 - Third party IPv6 UDP Application is receiveing broadcast messages

Test case 3) Bring-up 2 -Controllers with TCP IPv4 with one sub-net say 10.176.179.xxx address ,when A Third party IPV4 UDP Application bind to same Opensf dtm port 6900
different say 192.168.56.255 address to receive broadcast messages.

 - Third party IPv4 UDP Application is receiveing broadcast messages
