[Olsr-dev] Adding interface argument to packet_transform_function

[Kelvin Tran]

Hi,

I think it will make the Packet Transform handler a more flexible API  
interface if it provides the interface argument, especially in the  
case where OLSR run on multiple interfaces.

Below is the patch for olsrd-0.5.4 I have created and tested.
It will be nice if this can be merged into next release.
