| p | pointer to the packet will be received |

Here is the call graph for this function:
| void CbrModule::recv | ( | Packet * | p, | |
| Handler * | callback | |||
| ) | [virtual] |
Call the recv method with only the Packet parameter in order to hide the callback (not used in this implementation) and mantain compatibility with the old ns2 code
| p | pointer to the packet will be received | |
| callback | pointer to a Handler class |
Reimplemented from Module.

Moreover it inherits all the OTcl method of PlugIn
| argc | number of arguments in argv | |
