- Add a functionality to get SNMP community from DHCP (option 224) - Add a functionality to get minigraph from http service instead of using default minigraph - The url for graph service is passed through DHCP option 225 - This feature is by default disabled. Modify rule/config to enable it on build time, or modify /etc/sonic/graph_service_url on run time. - Fix a bug that getting hostname from DHCP is not working correctly
