Implements Destination-Sequenced Distance Vector.

The host using this routing algoritm 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.
