- What I did
Previous solution wouldn't necessarily wait until interfaces were completely up and configured with an IP address. This solution checks the INTERFACE_TABLE in STATE_DB, which should only report "ok" if the interface is completely up and ready.
Also enhanced the code to only wait for interfaces with an IPv4 address configured, as the DHCP relay agent currently only support IPv4.
