Options specific to the behavior of this module

• source.ip =<str>: source IP address, default '0.0.0.0'
• destination.ip =<str>: destination IP address, default '224.0.0.56'
• destination.port =<int>: destination port, default random between 46000 and 47024
• local.ifname = <str>: interface name to use
• net.mtu = <int>: MTU to use, default 1280
