*
|
|
* The mh module implements a multihop forwarding mechanism. Routes
|
|
* must have already been setup with the route_add() function. Setting
|
|
* up routes is done with another Rime module such as the \ref
|
|
* routediscovery "route-discovery module".
|
|
*
|
|
* \section channels Channels
|
|
*
|
|
* The mh module uses 1 channel.
