Change the default multicast group range
The 224.0.0.X range is a special range in multicast which acts like a
broadcast for non-IGMP traffic.
This patch changes the value of the multicast_group_range configuration
option to 225.0.0.X to avoid this special case.
See session "2.1.2. Data Forwarding Rules" at
https://tools.ietf.org/html/rfc4541 for more information:
2) Packets with a destination IP (DIP) address in the 224.0.0.X range
which are not IGMP must be forwarded on all ports.
