No such interface wlan error in veins module

[Sanjeeth]

Hello All,

Below in my scenario.ned file for which I have configured wlan interface. Declarations for wlan parameters are in the .ini file but I still get the below error. 

"Error in module (HostAutoConfigurator) RSUExampleScenario.ac_wlan (id=2) during network initialization: No such interface 'wlan'."

I have manually configured the parameters for phy and mac layer. Prior to this, I was still getting the same error. Kindly let me know if there are any changes in the source code for this wlan interface to be recognized or not throw an exception. It will be of great help.
