//
// Sends IP or IPv6 datagrams to the given address at the given `sendInterval`.
// The `sendInterval` can be a constant or a random value (e.g. exponential(1)).
// If the `destAddresses` parameter contains more than one address, one
// of them is randomly chosen for each packet. An address may be given in the
// dotted decimal notation (or, for IPv6, in the usual notation with colons),
// or with the module name. (The `L3AddressResolver` class is used to resolve
// the address.) To disable the model, set `destAddresses` to "".
//
// The peer can be ~IpvxTrafSink or another ~IpvxTrafGen (it handles received packets
// exactly like ~IpvxTrafSink).
