[ndnSIM] [EXT] [ndnSim] How to change the default values from NFD configuration fil

[Ygor Amaral]

Hi Leandro,

When you use ndn::StackHelper, it sets up the entire NDN stack on the node.
Including GenericLinkService and NetDeviceTransport.

See the StackHelper::DefaultNetDeviceCallback
and StackHelper::PointToPointNetDeviceCallback methods.

So if you use ndn::StackHelper, you do not need to configure
NetDeviceTransport.

Regards,
Ygor Amaral
