[ns] How I distinguish a packet in queue is a multicast packet?

[Sidney Doria]

If you can access the packet header, a packet is a multicast packet if

#define MULTICAST_ADDRESS 0xE000000

p->daddr() >= MULTICAST_ADDRESS


Take a look in MAODV code for ns2. It uses this definition in recv() function
