Dsdv¶

//
// Implements Destination-Sequenced Distance Vector.
//
// The host using this routing algorithm is required to have a SINGLE interface
// which has "wlan" in its name.
//
// NOTE:
//  - This is a fairly incomplete implementation of the originally published DSDV
//    algorithm. It does not implement full routing table dumps, hello message forwarding,
//    there is no logic that sends out full updates if the size of the incremental update reaches
//    the network unit size.
//
// WARNING: This is a partial / unfinished implementation.
