Dymo¶

//
// Provides Dynamic MANET On-demand (Dymo also known as AODVv2) Routing
// based on the IETF draft at http://tools.ietf.org/html/draft-ietf-manet-dymo-24.
//
// Module parameters are copied from the IETF draft and renamed for consistency with
// INET naming conventions. Some parameters are not yet implemented.
